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...

Despite a growing literature documenting strong linkages between income and health, there remains little understanding of how economic factors shape disease outcomes in the HIV/AIDS epidemic. Using individual level data from nineteen sub-Saharan African countries, we show that negative income shocks can lead to substantial increases in HIV prevalence. We match data on individuals’ HIV status fr...

The underlying motivation of this study is to account for the spatial variation of factors affecting women’s access to land, which has been largely ignored by the traditional regressionbased model studies, much to the detriment of spatially varying relationships. Using household and individual-level data from the Demographic and Health Surveys (DHS), this study used Geographically Weighted Regr...

Previous studies, conducted mainly in Asian countries, have shown that women‘s empowerment is associated with contraceptive use, lower fertility, and longer birth intervals. Yet little is known about the association of women‘s empowerment with fertility desires in subSaharan African countries where overall fertility levels remain high. This study tries to fill this gap, exploring whether women‘...

In a cross-sectional postal questionnaire study we compared individuals with localized low back pain (LBP) with individuals with LBP as part of widespread musculoskeletal pain, according to demographic and lifestyle characteristics and functional ability. All the inhabitants in Ullensaker county born 1918-20, 1928-30, 1938-40, 1948-50, 1958-60 and 1968-70 were sent a questionnaire in 1994. The ...

SAMPLE Two consecutive cohorts of Year 5 (final year) UCL ...

The identification of the characteristics that have an influence on the vaccination coverage of children and the determination of the pattern of such influence are very important since the government can reschedule the policy to immunize each and every child. This paper examines the factors that manipulate the vaccination coverage in terms of five major vaccines using the Bangladesh Demographic...
