Usage of English Language, Ethnic Identity and Ethnic Culture in American Orthodox Christian Churches  

This report is based on data from a national survey of Orthodox parishes administered in 2011.

Results of this study are presented jurisdiction-by-jurisdiction and also state-by-state. Special attention is given to the question of measuring the strength of ethnic identity and ethnic culture in US Orthodox churches. The report also examines the correlation between ethnic identity/English language usage and regularity of church attendance. The report is accompanied by four maps.

This report examines the budgets and overall financial health of parishes in the three largest American Orthodox jurisdictions—Greek Orthodox Archdiocese of America (GOA), Antiochian Orthodox Christian Archdiocese (AOCA), and Orthodox Church in America (OCA)—in the wake of the 2008-2009 recession. The report looks at the financial health of Orthodox parishes in 2000 vs. 2010; how the recession impacted parishes’ income, operations, and church members; and whether the three jurisdictions were equally affected by the recession. The report also compares the recession’s effect on Orthodox parishes versus Protestant congregations and Roman Catholic parishes. Results are based on a 2010 survey in which 368 GOA, AOCA, and OCA parishes participated.
