An additional source of information that is available at the county level is compiled by

congregations and adherents by county, provided through a survey sent to religious
organizations. Based on this data, the religious bodies with the five largest groups of
adherents in Lake County are:

of Serbian Orthodox Church in North America and Muslim adherents increased
significantly during this time, making these the two fastest-growing religious bodies in
