几乎在所有人口中都观察到出生率的季节性波动。在本文中，我们重新审视了出生的季节性，并考虑了两个主要目标。第一是概述出生季节性的基本事实，提出对季节性模式的新估计。季节性是一个重要的，如果不是占主导地位的来源，在几乎所有的人口出生的非趋势变化，但有戏剧性的和令人费解的差异，在不同国家和不同时期的季节性变化的模式中观察到的特定人群。本文的第二个目的是调查有关出生季节性的主要假设，已经出现在文献中，并讨论这些假设与观察到的季节性模式的一致性。利用我们对季节性模式的估计，沿着文献中的其他证据，我们得出结论，没有一个单一的解释得到强有力的，一致的数据支持。
Seasonal fluctuations in births have been observed in virtually all human populations. In this paper we re‐examine the seasonality of births with two main objectives in mind. The first is to provide an overview of the basic facts about the seasonality of births, presenting new estimates of the seasonal patterns. Seasonality is an important if not dominant source of nontrend variation in births in virtually all populations, but there are dramatic and puzzling differences across countries and time periods in thepatternof seasonal variation observed in particular populations. The second purpose of the paper is to survey the leading hypotheses about birth seasonality that have appeared in the literature and to discuss the consistency of these hypotheses with observed seasonal patterns. Using our estimates of seasonal patterns along with other evidence in the literature, we conclude that no single explanation receives strong, consistent support from the data.
