Four of Maryland’s five most populous jurisdictions — including Baltimore City and Baltimore County — lost population over the past year, according to annual estimates by the U.S. Census Bureau released Thursday.Though 18 of Maryland’s 24 counties increased in population, five grew by less than a quarter percent, contributing to the state’s overall population decline. The drop could lead state agencies to adjust previous predictions that Maryland, with a population of 6.16 million, would reach 6.24 million people by 2025.
