Baltimore is in the top third of 100 metro areas for exports, but its recent export growth has been below average, according to Brookings Institution.

The liberal think tank’s report published Monday said Baltimore produced $8.95 billion billion in exports in 2008, ranking No. 31 in the nation. Average wages in the largest export industry, chemicals, were $70,965, $4,500 above the national average. In terms of jobs, 74,032 jobs support Baltimore’s export industry, ranking 30th.
