Křesťanství a islám v USA a analýza metod k odhadu jejich zastoupení v populaci

Estimating the sizes of religious communities in the United States is a relatively infrequent subject of discussion. Nonetheless, understanding the religious landscape in the USA holds significant importance not only for analyzing religious trends and interfaith dynamics but also for various sectors such as services, government administration, and marketing. Due to the interpretation of the legal guarantee of religious freedom in the country, obtaining precise data about religious affiliations through governmentled social surveys and research is challenging. This responsibility falls upon civic organizations, which have limited authority and resources. These organizations employ diverse approaches to estimate the number of believers, and these estimates may not always be completely accurate. Given the scarcity of resources dedicated to this topic, it seems appropriate to evaluate the most currently accessible methods. This article evaluates three methods for estimating religious communities in the USA, focusing on comparing Christianity and Islam as representative examples.
