The Effect of Hot Days on Birth Rates in Serbia: Regional Aspect

摘要

The aim of this study is to examine the effects of hot days on birth rates in Serbia and its districts. This is the first study to address this issue in Serbia, with a regional focus stemming from the pronounced spatial heterogeneity in birth rates and climate conditions. The research utilizes data from demographic statistics on nearly 382,000 live births across 25 Serbian districts during the period 2015–2020, alongside data from the Digital Atlas of Serbia on daily average temperatures in the same timeframe. Inspired by methodologies from previous studies in other regions, this approach allows for an in-depth analysis of the impact of variations in daily air temperature distribution, particularly hot days with an average temperature exceeding 25 °C, on birth rates up to 12 months post-exposure. The results reveal that hot days (>25 °C) lead to a significant decline in birth rates approximately 9–10 months later. This is followed by a partial rebound, with a slight increase in birth rates observed in the 11th and 12th months. Regional variations within Serbia highlight differing levels of population adaptability, reflecting the diverse socio-climatic resilience across districts. These findings have important implications for developing locally tailored policies and responses to climate change. Enhancing population adaptability at the regional level may serve as a mechanism to mitigate the fertility impacts associated with climate change.
