According to US Census data released yesterday, Baltimore City lost about 30,000 residents between 2000 and 2010.  This population decline could result in the loss of one of the City’s  six seats in the Maryland State Senate.  As reported in Maryland Politics:

State law requires that Maryland’s 47 senators each represent roughly the same number of people. Ten years ago the ideal senate district included 112,691. The new ideal size for each seat is 122,842 — which would give Baltimore five seats.

The state’s population has become more diverse and several other jurisdictions experienced growth

Howard County grew by nearly 16 percent, fueled by a large increase in its Asian population. Growth was slower in Baltimore County — just 6.7 percent — but the county is still one of the state’s most populous, with more than 800,000 people.

In the southern part of the state, St. Mary’s and Charles counties recorded the fastest growth. Montgomery County, still Maryland’s most populous county, added nearly 100,000 people during the decade, reaching almost a million residents.
