The Average Rainfall in Countries Does Not Necessarily Result in an Increase in the Birth Rate

Studying the correlation between rainfall and birth rates is crucial for economic and social planning. Research indicates that higher rainfall may lead to increased birth rates in African nations dependent on agriculture, while developed countries with advanced irrigation technologies show weaker correlations. This study investigated the relationship between average annual rainfall and birth rate in ۱۸۲ countries worldwide. Data was gathered from the World Bank database and analyzed using statistical methods with SPSS v. ۲۲ software. Results showed that data on birth rate and annual rainfall were not normally distributed, so non-parametric tests were utilized for analysis. The study revealed a significant difference in annual rainfall amounts between continents, with the highest levels in Oceania and Central America. Birth rates also varied significantly by continent, with Africa having the highest rate. However, there was no significant correlation found between birth rate and rainfall across countries globally. Factors such as droughts and climate change can impact fertility rates and birth outcomes, highlighting the importance of environmental conditions in population dynamics. The complex relationship between rainfall and birth rates is influenced by agricultural productivity, economic stability, and regional disparities. Understanding these dynamics is essential for effective planning to address population trends.
