===========
/1/ This is a statutory designation given to the untouchables by the Government of India Act, 1935. NOTE: The figures for the Scheduled Castes both for British India and Indian States do not give the correct totals. The figures for Ajmer-Merwara in British India and for Gwalior State are not included in the totals. The Census Reports for 1940 fail to give these figures.
