“…Potential drivers of SSA birth seasonality fall within these categories: social factors that influence coital frequency and timing, such as marriage time preference and labor migration; climatological and energetic factors that affect conception probability given intercourse, such as temperature and energy expenditure; and factors that can increase the probability of fetal loss, such as disease incidence (Panter-Brick 1996;Ellison, Valeggia, and Sherry 2005;Lam, Miron, and Riley 1994).…”

“…6 Birth seasonality is also present in developing countries, though the United Nations data appear to suffer from misreporting in some country-years. 7 For a discussion on some of the hypothesized causes of birth seasonality, see Bronson (1995Bronson ( , 2009, Ellison et al (2005), Lam and Miron (1991a), Meade and Earickson (2000), and Rodgers and Udry (1988).…”

Dynamic adjustments could be a useful strategy for mitigating the costs of acute environmental shocks when timing is not a strictly binding constraint. To investigate whether such adjustments could apply to fertility, we estimate the effects of temperature shocks on birth rates in the United States between 1931 and 2010. Our innovative approach allows for presumably random variation in the distribution of daily temperatures to affect birth rates up to 24 months into the future. We find that additional days above 80 °F cause a large decline in birth rates approximately 8 to 10 months later. The initial decline is followed by a partial rebound in births over the next few months implying that populations can mitigate the fertility cost of temperature shocks by shifting conception month. This dynamic adjustment helps explain the observed decline in birth rates during the spring and subsequent increase during the summer. The lack of a full rebound suggests that increased temperatures due to climate change may reduce population growth rates in the coming century. As an added cost, climate change will shift even more births to the summer months when third trimester exposure to dangerously high temperatures increases. Based on our analysis of historical changes in the temperature-fertility relationship, we conclude air conditioning could be used to substantially offset the fertility costs of climate change.

“…The larger or smaller a population of species can determine the mating opportunity, as can be observed among the apes communities, (Ellison et al, 2005). Also, where population size is determined by environmental or agricultural factors, seasonality of mating opportunity can result.…”

“…According to Ellison, Valeggia, and Sherry (2005), social celebrations that creates jolly atmosphere for intercourse among humans determines cyclic occurrences of conceptions, and as such, influence the differences in birth rates. This is in unison with National Center for Health Statistics (1966), who asserted that conceptions usually hit peaks around celebrative religious holidays.…”

To examine the influence of social activities on birth rates in Makurdi town of Benue State Nigeria, a total of 23,000 recorded births from the year 2006 to 2015 were collated from six renown hospitals purposively selected based on issuance of ethical clearance and availability of data. With the use of secondary data, descriptive analysis was implored using tables and graphs. The result shows that births in Makurdi are characterized with two major peaks and two troughs. There is the March to June peak and the September to October peak. Alternatively, there is also the July to August trough and the December to January trough. Males generally dominate March births while females dominate December births. More pregnancies are conceived in the cool dry season which marks wedding celebrations, Christmas and New Year festivities while the hot dry season marking the Easter festivity and farming activities records the least conceptions. The implication is that conception is higher during festive periods that fall within months of low temperature. Therefore, the Ministry of health and other stake holders in Makurdi town should carry out awareness campaign on effective family planning during periods of high social activities or festivities to address the issue of high birth rates and over population in our society; Schools managements in Makurdi town should educate the students during festive periods to avoid teenage pregnancy.
