The rankings heard 'round the region

A REPORT last year by the Milken Institute found a gaping disparity between the Philadelphia region's strength in the life sciences overall, and the "vitality" of its life-science start-ups. With a low birth rate and high death rate for small life-science companies, the region came in ninth in the start-up ranking nationally. Milken's analysts said that future growth in the life sciences - a sector that now accounts for one of every six jobs here - depends on "smaller, nimbler and more specialized firms."
