COMPARABILITY FACTORS
To enable local vital statistics to be compared with other
districts or with national figures the Registrar General issues
comparability factors for correcting crude birth and death rates.
The Registrar General has intimated that the factors for certain
areas, where rapid increase or reduction in the population has
materially affected its composition by sex or age groups have been
adjusted on that account. In addition, the death rate area
comparability factors have this year for the first time been
adjusted specifically to take account of the presence of any
residential institutions in each area.
Tottenham s factors have been increased as follows
Birth rate factor from 0.95 to 0.97
Death rate factor from 1.03 to 1.09
