The table below illustrates the statistics available at small geographic levels for the 1940-2000 censuses. The 1940 census was the first census to divide cities of 50,000 or more inhabitants into census tracts. In 1940, New Orleans was the only city in Louisiana to have census tracts. SMSAs have been used as geographical areas of population census data since the 1910 decennial census. The only city to have census tracts outlined before 1940 was New York City in the 1910 decennial.*
