Nearly 11,000 people moved into Maryland from other states from 1980 to 1985, a major reversal from the previous five years when Maryland lost nearly 75,000 people to other states, officials said yesterday.

Michel Lettre, director of the state's Office of Planning Data, attributed Maryland's growing popularity as a residential area to the state's increased job opportunities.

Lettre said growth in high-tech industries, as well as federal and defense contract employment, has lured people to Montgomery County, while growth in the Baltimore area can be partially credited to "a better impression that people have of the city."

Montgomery experienced the biggest growth among state jurisdictions from 1980 to 1985, gaining 19,624 people from both out-of-state and in-state migration. Howard County ranked second in growth by migration, gaining 14,839.

Prince George's County was among the biggest losers in migration, with 27,007 people moving out during the five-year period. "There was a tremendous turnover in population. A great deal of out-migration of nonwhites from Washington, D.C., into the county and a great deal of out-migration of whites from the county. But that's changing a good deal now," Lettre said.
