BALTIMORE -- Maryland's economy, based on income per capita and job creation, surpassed the national performance from 1980 to 1988, Maryland's Planning Office reported.

Officials said income per capita in Maryland rose to $19,580 in 1988 from $10,790 in 1980, an increase of 81 percent.

Nationally, income per capita rose to $16,490 in 1988 from $9,919 a decade ago, an increase of 66 percent.

In the area of job creation, officials said Maryland registered an increase of 556,000 full-time and part-time jobs, a 27 percent rise from 1980 to 1988.

Nationally, full-time and part-time employment grew by 18 percent during the same period.

"Maryland's economic performance during the late 1980s was very impressive," said Ronald Kreitner, director of the Maryland Planning Office. "We are fortunate to be living in a dynamic state offering abundant, well-paying jobs."

"But as Maryland continues to grow we must never lose sight of the need to manage future growth ensure a healthy and vibrant economy and environment for future generations," he said.

Officials said Montgomery County remains Maryland's most affluent county with income per capita in 1988 of $27,813.

Somerset County registered the largest percentage increase, 108.7 percent, from $5,914 in 1980 to $12,343 two years ago.

But Somerset County still ranked last among all jurisdictions in income per capita.

Officials said Maryland's thriving economy is responsible for a net gain of more than 66,500 people moving into the state from 1985 to 1988, six times more than had migrated to Maryland during the slower economic times of 1980 to 1985.

"Maryland's economy was very strong during the late 1980s, as companies were formed and jobs were created," Kreitner said. "Consequently, people were moving here to take advantage of the employment opportunities."

In the first five years of the decade, eight jurisdictions recorded net increases in migration, while during 1985-88 only four jurisdictions lost population to other counties or states.

Montgomery County showed the largest net migration increase with 28,600 new residents during 1985-88.

Howard County had the second highest gain with 12,231.

The jurisdictions recording the largest declines were the city of Baltimore, which lost 28,104 residents, and Prince George's County, which had a net loss in population of 10,367, officials said.
