_D_e_s_c_r_i_p_t_i_o_n:

     Holford's data on prostatic cancer deaths and mid-period
     population denominators for non-whites in the US by age and
     calendar period. Thirteen birth cohorts from 1855-59 through to
     1915-19 are represented in at least one of seven 5-year age groups
     (50-54 through to 80-84) and one of the seven 5-year calendar
     periods (1935-39 through to 1965-69) for which data are provided.
