... is the total number of persons who attain exact age x during a specified time period, r(y) is the average rate of increase of persons at age y during the period, and Qx/Qo is the proportion of persons surviving from birth to age x in a hypothetical cohort subject at each age to the mean death rate at that age in the intercensal period.

... or, more precisely, from a model life table at an approximately appropriate level of mortality.9 When the number of people attaining age x has been determined for each cohort that passes through x between the censuses, N(x) is found by taking the total for all such cohorts.

CRUDE DEATH RATES The crude death rate from less to 1982 based on the officially recorded number of deaths is shown in Table 10 together with an estimated sequence in which the rates are adjusted for underreporting. year is based on a crude estimate of the annual proportion underreported, an estimate based on the assumption of rising completeness of recorded deaths until 1964 and The adjustment for each

... The officially recorded deaths show a large reduction in the crude death rate, interrupted by an increase during the crisis years of 1958-61, with a peak rate of over 25 deaths per 1,000 population in 1960. Because deaths were much less completely recorded in 1953-64 than in 1964-82, it is clear that the true decline in the death rate was much greater than indicated by the official rates.

... Had deaths followed a linear trend from 5.9 million to 8.0 million over these years, the total number of deaths in 1958-63 would have been 41.8 million. The number derived from officially recorded death rates is 57.4 million; by this calculation
