In the Appendix, we compare the distributions of deaths by cause and by age for the NDMC and the National Capital Territory of Delhi. The distributions of deaths by cause are similar, with between 20 and 25 percent of all medically certified deaths attributable to causes associated with air pollution (respiratory illnesses and cardiovascular disease). Roughly the same percentage of deaths are attributable to infectious diseases and to perinatal causes. The distribution of deaths by age group differs somewhat between the NDMC and the National Capital Territory. Forty-three percent of deaths in the NDMC occur before the age of five, compared.
