How many parishes does Louisiana have?
Louisiana uses the term "parish" instead of "county" — the only US state to do so. The term was inherited from the state's French and Catholic colonial period, when ecclesiastical parishes served as local administrative units. Today Louisiana's 64 parishes are functionally identical to counties in every other state.
The largest parish by land area is Vernon Parish at 1,328 square miles, home to about 46,704 residents. The most populous is East Baton Rouge Parish with approximately 451,022 residents — a density of about 991 people per square mile.
At the other end of the scale, Tensas Parish has only about 3,935 residents.
Louisiana’s capital is Baton Rouge, while the largest city is New Orleans — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.

Two SimpleMapLab studies cover Louisiana specifically: the 100-mile radius around Baton Rouge measures how much of the state lives within 100 miles of its capitol, and the loneliest town in Louisiana ranks the state’s most isolated inhabited place. The county-counts blog post puts Louisiana’s 64 parishes in national context.
