Mapping dental establishments in New York State just before the recession.

Census Bureau data indicate a continuing increase in the number and size of dental establishments in the period just prior the recent recession. During this same period, the combination of a relatively limited increase of the population in New York State and increasing numbers of dentists and dental establishments resulted in decreases in population ratios, particularly in New York City. The usual favorable expectations of an economic upswing after a recession for dental establishments may need to be tempered given these developments.
