The U.S. adult population grew by 6.3% from 2010 to 2016. Growth in the numbers of adults self-identifying as Catholic have not kept pace and are falling into negative territory, according to an analysis of survey data in combination with Census numbers for adults. Since 2010, the adult Catholic population in the United States has declined by 0.9% (equivalent to a net loss of 511,558 adults affiliating). The number of adult Catholics declined from 59.1 million in 2010 to 58.6 million in 2016.
Globally, the Church continues to grow and the United States represents less than 6% of the world’s Catholics. It is also easy to think these changes are related to something that the Church specifically is or is not doing. Yet many other affiliations are experiencing much more significant declines. Generally speaking, these trends are also likely to be related to broader shifts in popular culture, the economy, the family, and to bring it back to the iGen—technology. There is so much more to explore.
