Abstract This paper examines the trends in economic
inequality in infant mortality across urban–rural residence
in India over last 14 years. We analysed data from the three
successive rounds of the National Family Health Survey
conducted in India during 1992–1993, 1998–1999, and
2005–2006. Asset-based household wealth index was used
as the economic indicator for the study. Concentration
index and pooled logistic regression analysis were applied
to measure the extent of economic inequality in infant
mortality in urban and rural India. Infant mortality rate
differs considerably by urban–rural residence: infant mor-
tality in rural India being substantially higher than that in
urban India. The findings suggest that economic inequali-
ties are higher in urban than in rural India in each of the
three survey rounds. Pooled logistic regression results
suggest that, in urban areas, infant mortality has declined
by 22 % in poorest and 43 % in richest. In comparison, the
decline is 29 and 32 % respectively in rural India. Eco-
nomic inequality in infant mortality has widened more in
urban than in rural India in the last two decades.

Introduction
Despite the several efforts at reducing infant mortality rates
(IMRs) in India, the high levels of infant mortality continue
to pose a major challenge to the public health system. Of
the five million children of the developing countries that
die before reaching their first birthday annually [1], India
alone contributes about one-third [2]. Not only is the bur-
den of infant deaths high in India, but also level of
infant mortality differs starkly across states and urban–
rural residence [3]. For example, IMR in 2009 ranged
between a low of 12 infant deaths per 1,000 live births in
Kerala to a high of 67 in Madhya Pradesh. The IMR was 55
per 1,000 live births in rural India compared to only 34 in
urban India [3].
Acknowledging the higher health needs of the rural
masses, the Government of India launched its most ambi-
tious health programme in 2005, commonly known as
National Rural Health Mission (2005–2012). The main goal
of this programme is to ensure provision of high-quality
health services to the rural masses, in particular to the poor
and marginalized. In order to achieve this goal, the pro-
gramme is meant to bring architectural corrections in the
public healthcare system in rural areas. The architectural
corrections (as distinct from what was called health sector
reform in the earlier period) include decentralization and
organizational reforms in the health sector, inter-sectoral
convergence, public–private partnership in health sector, and
the induction of management and financial personnel into
the healthcare management and delivery system. It also aims
at mainstreaming Indian system of medicines, strengthening
community healthcare through community-level activists,
involving Panchyati Raj Institutions and Community Action,
exploring new health financing mechanisms, district plan-
ning, medical education, and technical support [4]. Through

this programme, the Government of India has substantially
increased its investments in Reproductive and Child Health
program.
Unfortunately, the Government of India has completely
overlooked the heath needs of the urban population under
the impression that urban populations enjoy better health
than their rural counterparts, presumably because urban
centres are characterised by well-equipped modern health-
care systems coupled with better accessibility to, and
availability of, nutritious food, housing, and employment
opportunities, better education and higher income, improved
water and sanitation facilities [5–9]. In addition, the igno-
rance of urban health status could also have been due to lack
of systematic evidence on the socioeconomic inequalities in
maternal and child health within urban India.
Several studies conducted in recent years have docu-
mented the inferior maternal and child health of the urban
poor in developing countries [10–13]. In developing coun-
tries, though the average health status is better in urban
areas, economic inequality is higher in urban than rural areas
[14]. Using the Demographic and Health Survey (DHS) data
from ten developing countries, a study has shown that the
socioeconomic gradient in childhood undernutrition is
higher in urban areas than in rural areas [15]. Another study,
based on Sub-Saharan African countries, has found that
socioeconomic inequalities in childhood undernutrition are,
to a large extent, higher in cities than in rural areas [5]. A
few recent studies from India have documented socioeco-
nomic disparities in the utilization of maternal healthcare
services and childhood nutritional status in urban areas of
the country [16–18]. These studies clearly show that the
health status and utilization of healthcare services is much
lower among the urban poor than the rest of the urban
population and the gap has widened over time. These studies
raise important concerns about the availability and accessi-
bility of health services to the urban poor.
Literature search yielded only one study that exclusively
investigated economic inequalities in utilization of mater-
nal and child healthcare services by urban–rural residence
in India [17]. Furthermore, we could not come across any
published study that examined economic inequality in
infant mortality separately by urban and rural residence in
India, despite the fact that infant mortality is one of the
most important indicators of socioeconomic development
of a country and that millennium development goals-4
(MDG4) exclusively talks about reducing IMRs. Studies on
economic inequality in infant mortality by urban–rural
residence are particularly important in a country like India
where IMRs differ considerably by urban–rural residence.
Indeed, India is undergoing rapid urbanization, with a
significant proportion of India’s population now living in
urban areas [19]. Notably, lower levels of infant mortality
in urban India compared to rural India may not necessarily
result into lower economic inequality in urban India than in
rural India. The present study, therefore, aims to investigate
the economic inequality in infant mortality by urban–rural
residence in India using the three rounds of the National
Family Health Survey (NFHS) conducted in India during
1992–1993, 1998–1999, and 2005–2006.
Data and Methods
Ethics Statement
The multi-rounds of the NFHS was conducted under the
supervision of the International Institute for Population
Sciences (IIPS), Mumbai, India—a regional centre of
teaching, training, and research in population studies. The
ORC Macro institutional review board approved the data
collection procedures. A formal written consent was
obtained before interviewing the respondent in the survey.
Moreover, this study is based on anonymous public use
datasets with no identifiable information on the survey
participants. Survey data are available upon the request on
the official website of the institute.
Data
We used data from the three successive rounds of the
NFHS conducted in India during 1992–1993, 1998–1999,
and 2005–2006. The NFHS is similar to the DHS of other
countries. The NFHS is a large scale and multi-round
survey conducted on representative sample of households
spanning across the states and union territories of India.
The main purpose of the NFHS is to provide reliable
estimates on fertility, infant and childhood mortality,
family planning, utilization of maternal and child health-
care services, and childhood nutritional status at the
country and state levels. The NFHS also provides these
estimates by urban and rural residence.
The NFHS adopted similar sampling design in each of the
three survey rounds. A two-stage sampling design was
adopted in rural areas—villages were selected at the first stage
using probability proportional to size (PPS) sampling scheme
followed by selection of households at the second stage using
systematic sampling scheme. The sample in urban areas was
selected in three stages. The first stage comprised of selection
of urban wards using PPS sampling scheme. Census enu-
meration blocks (CEB) containing approximately 150–200
households were selected at the second stage. Households
were selected at the third stage using systematic sampling
scheme. The similarity in the sampling design of the three
survey rounds allows for a comparison of the estimates
obtained from the three consecutive rounds [20, 21]. The

details of sampling design are given in the reports of the
various rounds of NFHS [22–24].
Information in the three rounds of NFHS was collected
through face-to-face interview, using similar interview
schedules. In NFHS 1992–1993 and 1998–1999, the infor-
mation was collected using community, household, and
eligible women schedules. In NFHS 2005–2006, informa-
tion was collected using household, eligible women, and
eligible men schedules. The contents of the interview
schedules remained similar in all the three rounds. The
household response rate was 96 % in the first round and
98 % each in the second and third rounds of the NFHS. The
individual response rates were 96 % each in the first and
second rounds, while it was 94 % in the third round.
Outcome Variable
The outcome variable in this study is infant mortality. IMR
is defined as the probability of death before reaching 1 year
of age. A unique feature of NFHS is that the survey col-
lected detailed information on all births to women (in the
age-group 15–49) interviewed in the respective samples.
This detailed birth history provided us an opportunity to
conduct the statistical analysis presented in the results
section. We first collected information on births that took
place in 10 years preceding the respective survey round.
Then we excluded the births taken place in the last 1 year
preceding the respective survey dates to remove the cen-
sored cases. The outcome variable is a binary variable (1 if
died during infancy; 0 if survived during infancy).
Exposure Variables
Economic status of the household is used as the main
exposure variable in the analysis. Previous studies have
shown a direct relationship between economic status of the
household and infant mortality [25–28]. Like other DHS,
the NFHS does not provide direct data on income or con-
sumption in India. However, the NFHS provides informa-
tion on a set of economic proxies such as housing quality,
household amenities, consumer durables, and size of land
holding. Studies in the past have used these proxy infor-
mation to assess the economic status of the households (in
terms of wealth quintiles) and to capture the economic
differentials in the population and health outcomes [29–
34]. Following the DHS approach, we used principal
component analysis to estimate wealth index separately for
urban and rural areas in each of the three NFHS rounds.
Wealth index was estimated separately for urban and rural
areas to account for the economic diversity between urban
and rural areas [35, 36]. The wealth index was estimated in
such a way that it was comparable over the three NFHS
rounds. The wealth index was subsequently divided into
five quintiles—poorest, poorer, middle, richer, and rich-
est—for conducting pooled logistic regression analysis.
A number of other socio-economic and demographic
variables have also been shown to have significant effect on
infant mortality in developing countries. Accordingly, we
controlled for a set of theoretically pertinent socio-economic
and demographic variables in the analysis. The variables that
were controlled in the pooled logistic regression analysis
are—sex of the newborn, birth order, and preceding birth
interval (first birth order; higher birth order and birth interval
B24 months; higher birth order and birth interval
[24 months), size of the newborn at birth (larger than aver-
age; average; smaller than average), mother’s age at birth of
the newborn (B19, 20–29, and C30 years), mother’s school-
ing (no schooling; 1–5 years of schooling; 6–12 years of
schooling; [12 years of schooling), father’s schooling (no
schooling; 1–5 years of schooling; 6–12 years of schooling;
[12 years of schooling), religion (Hindu; Muslim; Others),
skilled attendance at birth (no; yes), mother’s exposure to
media (no; yes), working status of mother (no; yes), and
geographic region of residence (north; east; central; northeast;
west; south). All the three rounds of NFHS collected infor-
mation on women’s exposure to radio, television, and news-
paper. The information on exposure to the three media sources
was used to compute mother’s exposure to media. Those
mothers who were exposed to at least one media source were
coded as ‘having exposure’ to media. Rest were coded as ‘not
having exposure’ to media.
Statistical Analysis
Infant mortality rates (with 95 % confidence intervals) by
urban–rural residence and by wealth quintiles separately
for urban and rural areas in each round of NFHS were
estimated using the life table technique available in STA-
TA 10.0 [29]. The IMRs were estimated simply to give the
levels and trends in infant mortality by urban–rural resi-
dence and by wealth quintiles in urban and rural areas.
Concentration index (CI) was used to examine the extent
of economic inequality in infant mortality by urban–rural
residence. The CI is widely used to examine the extent of
socio-economic inequality in any health outcome. It is
defined as twice the area between the concentration curve
and the line of equality [29, 37–39]. The value of CI varies
between -1 and ?1. A negative value implies that con-
sidered health variable is concentrated among the poor
while a positive value indicates that it is concentrated
among the rich. A value of ‘0’ implies that health outcome
is equally distributed between the economic groups. We
used factor score of household wealth, obtained from the
principal component analysis, to estimate CI.
A previous study [40] has shown that the lower and
upper bounds for CI can depend on the mean values in case
Matern Child Health J

of dichotomous outcome variables (as in our case). This
implies that the extent of inequality as measured by the CI
can get affected considerably if the mean of the outcome
variable changes from one survey round to the other. One
solution to address this problem is to normalize the CI or to
divide it by the reciprocal of the mean. We addressed this
issue in the present analysis by normalizing the CI values.
We used binary logistic regression analysis to examine
the economic inequality in infant mortality after adjusting
for important socio-economic and demographic variables.
In the regression analysis, we pooled the data from the
three rounds of NFHS to examine the interaction effect of
time and household wealth in urban and rural India sepa-
rately. We present the pooled logistic regression results as
predicted probabilities for better interpretation. The expo-
sure variables were tested for possible multi-collinearity
before putting them into the regression analysis using the
variation inflation factor (VIF) post estimation command.
We used appropriate weights in the analysis to make the
estimates representative and comparable across the three
survey rounds, and to account for the multi-stage sampling
design adopted in the three rounds of NFHS. The details of
the sampling weights are given in NFHS reports of the
various rounds [22–24]. The analyses presented in the
subsequent sections were carried out in STATA 10.0.
Results
The urban sample comprised 31,373, 27,794, and 37,303
live births in the NFHS 1992–1993, NFHS 1998–1999, and
NFHS 2005–2006 respectively. Likewise, the rural sample
comprised 83,296, 80,208, and 61,266 live births in the
NFHS 1992–1993, NFHS 1998–1999 and NFHS 2005–2006
respectively. In urban areas, 1,793 (6.0 % of total live
births), 1,341 (4.9 % of total live births), and 1,691 (4.9 %
of total live births) infant deaths were observed in NFHS
1992–1993, NFHS 1998–1999, and NFHS 2005–2006
respectively. In rural areas, the number was 7,201 (9.5 % of
total live births), 6,182 (8.0 % of total live births), and 3,952
(7.1 % of total live births) in NFHS 1992–1993, NFHS
1998–1999, and NFHS 2005–2006 respectively. The details
of live births and infant deaths across the household wealth
and urban–rural residence are listed in Table 1.
Trends in Infant Mortality in Urban and Rural India
Infant mortality rate in India has declined considerably
both in urban and rural India as shown in Fig. 1. The IMR
in urban India has declined from 57 per 1,000 live births in

1992–1993 to 45 in 2005–2006. Likewise, IMR in rural
India has declined from 87 in 1992–1993 to 65 in
2005–2006. Although the urban–rural gap in IMR has
declined over the three NFHS rounds, a significant gap still
persists.
Trends in Economic Inequality in Infant Mortality
in Urban and Rural India
Figure 2 presents the trends in IMR across the household
wealth quintiles according to the place of the residence in
India during 1992–2006. We present the results only for the
poorest and the richest quintile to make the presentation
simpler. The results, disaggregated by wealth quintiles,
suggest that the IMR among the poorest quintile in urban
areas was 64 per 1,000 live births in NFHS 2005–2006.
This figure compares with an IMR of only 23 in the richest
quintile in the same period. In rural areas the corresponding
IMRs were 78 and 39 respectively. The pace of decline in
infant mortality was not the same in various economic
groups.
The CI values according to urban–rural residence are
presented in Table 2. Results clearly suggest significantly
higher economic inequality in infant mortality in urban
areas compared to that in rural areas in each of the three
NFHS rounds. The CI value for urban area was –0.194 in
2005–2006. The corresponding figure was only –0.081 in
the rural areas. The CIs for urban areas have only mar-
ginally declined from –0.199 in 1992–1993 to –0.194 in
2005–2006. The corresponding decline in rural areas was
from –0.087 in 1992–1993 to –0.081 in 2005–2006.
Regression Analysis
Earlier studies on infant mortality have shown that
important socioeconomic and demographic variables have
significant effect on infant mortality. In order to examine
the effect of household wealth on infant mortality over the
period 1992–2006, we estimated binary logistic regression
having adjusted for important socioeconomic and demo-
graphic characteristics. Only those variables that were
significantly associated with infant mortality in the bivar-
iate analysis (‘‘Appendix’’) were included in the final
logistic regression model, the results of which are shown in
Table 3. The results, adjusted for other important socio-
economic and demographic characteristics, clearly suggest
significantly higher risk of infant deaths among the poorest
quintile compared to that among the richest quintile both in
urban and rural India. In urban India the adjusted proba-
bility of infant death was 0.051 among the poorest quintile
in 2005–2006. In comparison, the probability was only
0.016 among the richest quintile. Likewise, in rural India,
the probability of infant death among the poorest and the
richest quintiles in 2005–2006 was 0.060 and 0.030
respectively. The pattern remained similar in each of the
three survey rounds.
The changes in predicted probabilities, presented in
Table 4, suggest that, in urban areas, for poorest quintile,
the probability of infant death declined by about 22 %
points during 1992–2006. Over the same period, the
probability of infant deaths among the richest quintile
declined by about 43 % points. The corresponding declines
in poorest and richest quintiles in rural areas were 29 and
32 % respectively. These findings suggest that the eco-
nomic inequality in infant mortality has widened in both
urban and rural areas during 1992–2006. However, the
economic inequality has widened more in urban than in
rural India.
Discussion and Conclusion
Our study examined the trends in economic inequality in
infant mortality according to urban–rural residence in India
using the three rounds of the NFHS conducted during
1992–2006. Clearly, the IMR has declined considerably in
both urban and rural India during late 1990s and early
2000s. This decline in IMR might be the result of interplay
of numerous factors such as the rapid economic growth
(with the introduction of the New Economic Policy in the
early 1990’s), improvement in agriculture, medicine, and
information technology. In addition, the maternal and child
health interventions such as Child Survival and Safe-
motherhood Program (CSSM 1992) and Reproductive and
Child Health Program (RCH 1997) might have also played
a significant role in lowering the infant mortality in urban
and rural India.
Like the aggregate level, the IMR has declined among
all the wealth groups in both urban and rural India.

However, the better-off families have experienced greater
decline in infant mortality compared to households
belonging to lowest wealth quintile in both urban and rural
areas. Interestingly, economic inequality has widened in
urban as well as rural areas during the study period. When
viewed in a context of the economic reforms which took
place in India since 1990s, our findings clearly indicate that
fruits of economic development are not being shared
equally by the different sections of the Indian society. In
both urban and rural India, the richest families have ben-
efitted from the economic and social development to a
greater extent than the poorest families. In addition, the
faster decline in infant mortality among the rich might also
be associated with their increasing access to technologies
to reduce neonatal mortality to which neither urban poor
nor the rural poor have access to [41].
Our findings indicate that the differences in IMR across
household wealth were comparatively higher in urban than
in rural India. In addition, the extent of economic
inequality was considerably higher in urban India com-
pared with rural India. This result was consistent in each of
the three NFHS surveys. Regression analysis further sug-
gests that the economic inequality in infant mortality has
increased over the last two decades in India; the increase
was particularly more pronounced in the urban areas as
compared to rural India. Our finding is consistent with the
findings of previous studies that have also highlighted the
vulnerability of urban poor when it comes to infant mor-
tality [10, 42]. Recent studies from India noted that eco-
nomic inequality in use of maternity services is higher in
urban than rural area of the country [17]. This could be a
possible reason for higher and widening economic
inequality in infant mortality in urban India as utilization of
maternal healthcare services has a direct and significant
influence on survival during infancy [43–45]. In addition,
the higher economic inequality in infant mortality in urban
areas might be a reflection of the greater economic

inequality that tends to prevail in urban settings [46].
Income constraints and price barriers deprive the urban
poor from access to health care despite their close prox-
imity of health care facilities. Financial barriers may also
limit the advantage that the poor can reap from the better
food supply in urban areas, while the rural poor can benefit
from their own food production and support networks [42].
The fact that the urban rich can benefit from the health care
advantages available in urban areas, while the rural rich
and poor in both rural and urban areas cannot, might
explain the greater economic inequality in child health in
urban areas. The urban poor also have the disadvantage of
poor living and sanitary conditions. Most urban poor are
found to live in extreme unsanitary and congested condi-
tion, leading to tremendous burden of ill-health and mor-
tality, especially among children [47].
Our findings show that, although the IMR is lower in
urban areas compared to rural areas, the economic
inequality in infant mortality in urban India is much higher
than in rural India. These findings clearly indicate that
within urban areas, a considerable proportion of the pop-
ulation bear a disproportionate burden of infant mortality,
and require special attention. Instead of using simple
averages, policy makers and programme managers must
use indicators disaggregated by socio-economic status to
formulate policies and programmes in India. It is probably
because of the better averages in urban areas that the
special needs of the urban poor have been overlooked.
Interestingly, the disparity between the urban poor and
the rich is much more than the disparity between rural poor
and rich. This finding implies a need for programs that
target the urban poor. This is becoming more necessary as
the size of the urban population is increasing in India.
Policies that aim to improve the health of urban poor might
be different than those of their rural counterparts. In urban
areas greater attention needs to be given to the generation
of employment, improving living conditions, education
levels, and economic well-being among the disadvantaged,
providing safe drinking water and public hygiene in slum
dwellings, and securing access to healthcare for the chil-
dren of informal sector workers [48, 49]. With the world
population set to becoming overwhelmingly urban, the
salient findings of the study will help to build a suitable
case for multifaceted policies targeted at improving the
health of the urban poor.
