  1. Teen pregnancy will decline as economic development increases (33).Barber, Nigel - On the relationship between country sex ratios and teen pregnancy rates, 2000 - 2 Variables

    This study attempted to replicate earlier findings regarding population structure and teen pregnancy rates. Findings support the previous predictions that sex ratio, economic development, and latitude are all inversely related to teen birth rates.

  2. "Teen birth rates will be lower at high latitudes" (30).Barber, Nigel - On the relationship between country sex ratios and teen pregnancy rates, 2000 - 2 Variables

    This study attempted to replicate earlier findings regarding population structure and teen pregnancy rates. Findings support the previous predictions that sex ratio, economic development, and latitude are all inversely related to teen birth rates.

  3. The sex ratio at birth will decline with polygyny.Barber, Nigel - Sex Ratio at Birth, Polygyny, and Fertility: A Cross-National Study, 2004 - 2 Variables

    This article discusses the variation in sex ratios at birth among human populations and the possible explanations for this variation. One possible explanation is the timing of intercourse and its relationship to the frequency of intercourse, which can affect the timing of conception. The article presents evidence that the male/female sex ratios of 148 countries declined with total fertility rates and polygyny intensity and increased with contraception use in correlational analysis. These results were independent of mother's age and level of economic development. The predictive effect of polygyny and contraception disappeared when total fertility was added to the equation. The article also considers other possible explanations for the variation in sex ratios, such as genetics, hormones, nutrition, and social factors.

  6. Economic development will tend to be associated with more disbelief in God.Barber, Nigel - A Cross-National Test of the Uncertainty Hypothesis Religious Belief, 2011 - 4 Variables

    The study looks at 137 countries and examines the relationship between disbelief in God and increased security in health, economic development and security. The findings provide additional support for the uncertainty hypothesis as there is a positive relationship between a country's health or financial growth/security and the population's disbelief in God.

  9. Economic development will be associated with less religiosity.Barber, Nigel - Country Religiosity Declines as Material Security Increases, 2012 - 4 Variables

    The present study attempts to replicate the Barber (2011) finding that more considerable security influences a country's disbelief in God. However, this research uses a more diverse sample and seeks to answer additional questions about religiosity and security than the previous work. The results are in line with all of the predictions and offer extra support to the uncertainty hypothesis.
