between 1930 and 1940. District 12 of Baltimore County, with an increase
of 33.6 percent, was the fastest growing urban place having 10,000 or more
population. Salisbury, with an increase of 21.1 percent, was the fastest
growing incorporated place in this size-group.

Eighteen of the 23 counties gained population between 1930 and 1940,
as did the independent city of Baltimore, which has the status of a county.
Montgomery County, with an increase of 70.5 percent, had the most ex-
tensive growth.

The first census of Maryland was taken in 1790, returning a population
of 319,728. The population has shown an increase at every census since that
time, passing 500,000 between 1840 and 1850, 1,000,000 between 1880 and
1890, and 1,500,000 between 1920 and 1930. The present population rep-
resents a density of 184.2 inhabitants per square mile. Maryland's total
land area is 9,887 square miles.
