    Quoted from the NIH website's handout on RA:

    "Scientists estimate that about 1.3 million people, or about 0.6 percent of the U.S. adult population, have rheumatoid arthritis. Interestingly, some recent studies have suggested that although the number of new cases of rheumatoid arthritis for older people is increasing, the overall number of new cases may actually be going down. Rheumatoid arthritis occurs in all races and ethnic groups. Although the disease often begins in middle age and occurs with increased frequency in older people, children and young adults also develop it. Like some other forms of arthritis, rheumatoid arthritis occurs much more frequently in women than in men. About two to three times as many women as men have the disease."

    The juvenile form of RA is more common in Caucasian children, however.

    Hope that helps.
