This life expectancy table is based on a survey of 4, 229 (2, 398 males and 1, 831 females) profoundly retarded persons living at home, who were registered with Tokyo Metropolitan Rehabilitation Center for the Physically and Mentally Handicapped during the four-year period 1974 to 1977.<BR>Age-specific mortality rates show that the youngest groups of profoundly retareded persons living at home had more than seventy times higher mortality rates in age group 1 to 5 for males and more than hundred times higer in age group 1 to 11 for females, than the same age groups of general population.<BR>For a cohort of 100, 000 babies born mentally retarded, the table shows that only about 50 percent of the total population could be expected to reach age 25 for males and 19 for females, whereas in the general Tokyo population about 50 percent could be reached age 77 for males, 81 for females, respectively.<BR>The life expectancy at birth for male profoundly retaded persons was 29.50 years and for females 27.06 years, whereas in Tokyo population this was 72.87 and 77.40 years, respectively. The life expectancy at birth of profoundly retaded persons in Tokyo was even shorter than that of the Toyama Prefecture's polpulation in the period 1921 throughout 1925, which was the shortest life expectancy ever experienced in Japan : for males 35.95 years and for females 37.87.
