英文摘要：
  Population growth (or decay) in a country can be due to various f socio-economic constraints, as demonstrated in this paper. For example, sexual intercourse is banned in various religions, during Nativity and Lent fasting periods. Data consisting of registered daily birth records for very long (35,429 points) time series and many (24,947,061) babies in Romania between 1905 and 2001 (97 years) is analyzed. The data was obtained from the 1992 and 2002 censuses, thus on persons alive at that time.   We grouped the population into two categories (Eastern Orthodox and Non-Orthodox) in order to distinguish religious constraints and performed extensive data analysis in a comparative manner for both groups. From such a long time series data analysis, it seems that the Lent fast has a more drastic effect than the Nativity fast over baby conception within the Eastern Orthodox population, thereby differently increasing the population ratio. Thereafter, we developed and tested econometric models where the dependent variable is the baby conception deduced day, while the independent variables are: (i) religious affiliation; (ii) Nativity and Lent fast time intervals; (iii) rurality; (iv) day length; (v) weekend, and (vi) a trend background. Our findings are concordant with other papers, proving differences between religious groups on conception, - although reaching different conclusions regarding the influence of weather on fertility. The approach seems a useful hint for developing econometric-like models in other sociophysics prone cases.

中文摘要：
如本文所示，一个国家的人口增长（或衰退）可能是由于各种社会经济制约因素造成的。例如，在各种宗教中，在耶稣降生和斋戒期间禁止性交。数据包括1905年至2001年（97岁）罗马尼亚很长时间序列（35429个点）和许多婴儿（24947061个）的登记每日出生记录。数据来自1992年和2002年的人口普查，因此是关于当时活着的人的。为了区分宗教限制，我们将人群分为两类（东正教和非东正教），并以比较的方式对两组人群进行了广泛的数据分析。从如此长的时间序列数据分析来看，似乎在东正教人口中，斋戒比降生斋戒对婴儿受孕的影响更大，从而不同程度地增加了人口比例。此后，我们开发并测试了经济计量模型，其中因变量为婴儿受孕日，自变量为：（i）宗教信仰；（ii）耶稣诞生日和四旬斋斋的快速时间间隔；（三）乡村性；（iv）日长；（v） 周末，以及（vi）趋势背景。我们的发现与其他论文一致，证明了不同宗教群体在受孕方面的差异，尽管就天气对生育能力的影响得出了不同的结论。该方法似乎是在其他社会物理学倾向的情况下开发类似于计量经济学的模型的有用提示。
