Human fertility has declined in all of the Middle East and North African (MENA) countries in the recent years, Iran had the largest decline, however. What factors have affected the fertility decline in Iran, and as compared with other MENA countries, is the question of this paper. Fertility, higher education, and other measures were used for comparison. Regression analysis was also carried out ...

In 2014, Egypt's Demographic and Health Survey (EDHS) documented an increase in the total fertility rate (TFR) to 3.5, up from a low of 3.0 recorded by the 2008 EDHS. The increase has been anecdotally attributed to the social upheaval following Egypt's January 2011 revolution, but little is known about when fertility first began to increase and among which sub-groups of women. Using birth histo...

This paper presents estimates of delayed childbearing and permanent childlessness in the United States and the determinants of those phenomena. The estimates are derived by fitting the Coale-McNeil marriage model to survey data on age at first birth and by letting the parameters of the model depend on covariates. Substantively, the results provide evidence that the low first birth fertility rat...

Bangladesh has been passing through a critical phase of fertility transition. The level of fertility started to decline since mid-seventies. The decline occurred at a rapid pace during the period 1975 to 1993/94. The total fertility rate was 6.3 in 1975 and decreased to 3.4 in 1993/94. However, since 1993/94, the level of total fertility appears to be unchanged at a level of 3.3, as observed fr...

Initially a general regression equation is estimated, making use of cross-country data, relating the level of the total fertility rate to a range of variables, including the level of per capita real income. There is a statistically significant negative relationship between the level of the total fertility rate and real income per capita. Once the theory of the quantity-cum-quality of children h...

Fertility rate is one of the most important global indexes. Past researchers found models which fit to age-specific fertility rates. For example, mixture probability density functions have been proposed for situations with bi-modal fertility patterns. This model is less useful for unimodal age-specific fertility rate patterns, so a model based on skew-symmetric (skew-normal) pdf was proposed by...

Human intelligence (IQ) correlates with a number of important life outcomes ranging from mortality and morbidity to social rank and status. Noticeably absent from the literature, however, has been a unifying framework from which to examine why IQ should correspond to so many seemingly disparate outcomes. Rushton’s Differential-K theory represents a theoretical perspective capable of accounting ...

Background & aim: The reduction of fertility rate in the recent years in Iran may be due to the cultural and socioeconomic development in this country. The present study was conducted to investigate the relationship of fertility rate with demographic, socioeconomic, and religious factors among childbearing women in a city in Easter Iran. Methods: This cross-sectional study was conducted on 254 ...
