Tuberculosis in immigrants in Birmingham 1970-72.

An analysis of notifications of tuberculosis in the City of Birmingham during the three-year period 1960-62 related to the population data from the Census of 1961 showed important differences between the notification rates of groups defined by their place of birth, and also differences in the age distributions of notification rates between these groups (Springett, 1964). A survey of notifications throughout England and Wales during a threemonth period in 1965 (British Tuberculosis Association, 1966) showed similar differences on a national scale; the survey of notifications throughout England and Wales was repeated during a fourmonth period around the time of the 1971 Census, and these results are being prepared for publication. The object of the present paper is to repeat the 1960-62 analysis of notifications in Birmingham for the period 1970-72 in relation to the results of the Census of 1971.
