the effectiveness of contraceptive methods, such as i.u.d. can be considered with different points of view, such as: the period of protection from pregnancy for such married couple. the demographic effect of the program, on the basis of the number of births, averted in a given population. the objective of the, present study was to calculate the probability of pregnancy, expulsion, removal and t...

This study investigates the role of wealth in infant mortality in Sub-Saharan Africa, hereafter (SSA). Using recent data from Demographic and Health Surveys (DHS), we document the differences that exit within urban and between urban and rural residents in Sub-Saharan Africa based on wealth. Our findings lead us to conclude that there is a statistical significant difference both within urban res...

Ð We use Demographic and Health Surveys (DHS) to compare ``poverty'' at two or more points in time within and between African countries. Our welfare measure is an index resulting from a factor analysis of various household characteristics, durables, and household headsÕ education. An advantage of this measure is that for intertemporal and intraregional comparisons, we need not rely on suspect p...

The Census Bureau used three methods to determine the nation’s population in 2000: the traditional headcount, the post-enumeration survey (Accuracy and Coverage Evaluation or A.C.E.), and Demographic Analysis (DA). The three estimates produced significantly different and confounding results. The divergence among the three — especially, the discrepancy between DA and the A.C.E. — is considered t...

To investigate the breeding structure in the Japanese Thoroughbred population, we applied a demographic analysis to the populations of foals produced from 1978 to 2005. The migration rate estimated from the proportion of foals produced by imported breeding horses was around 40% over the investigated period. After early 1990s, the migration rate through stallions imported from USA sharply increa...

This paper reassesses the nexus between female education, employment and fertility in Nigeria. The four Demographic and Health Surveys (DHS) that have been conducted in the country (1990–2008) were analysed. Between 1990 and 2008, the educational status of women improved appreciably and the proportion of illiterate women in the country declined from 57.2 to 35.8 per cent. Multivariate analysis ...

Commonly available survey data for developing countries often do not include income or expenditure data. This data limitation puts severe constraints on standard poverty and inequality analyses. We provide a simple approach to simulate household income based on publicly available Demographic and Health Surveys (DHS) and macroeconomic data. We illustrate our approach with DHS data for Bolivia, B...
