During increasing patient encounters (office visits, hospitalizations) increased. However, rates these encounters, when based population asthma, did not increase. rate 1980-1995, decreased each year 2000. 2001-2003, higher children (8.5%) compared adults (6.7%), females (8.1%) males (6.2%), blacks (9.2%) whites (6.9%), those Puerto Rican descent (14.5%) Mexican (3.9%), below federal poverty level (10.3%) at above (6.4% 7.9%), residing Northeast other regions (6.7% 7.5%).
