2. COMPARABILITY FACTOR - BIRTHS AND DEATHS
The Registrar-General supplies each town with figures known as the
"area comparability factor* in connection with the birth and death rates.
These factors make allowance for the way in which the sex and age distribution
of the local population differs from that for England and Wales as a
whole. The death rate area comparability factors are also adjusted specifically
to take account of the presence of any residential institutions in
each area, and the birth rate area comparability factors are adjusted
specifically to take account of the presence of sterile population in
institutions for the mentally ill or mentally deficient in each area.
The figures for Ilford are 1.00 for the birth rate and0.99 for the death
rate, and these are used in calculating these rates in Table 1A.
When local crude birth and death rates have been adjusted (by multiplication
by the appropriate area comparability factors) they are comparable
with the crude rate for England and Wales or with the corresponding
adjusted rate for any other area.

transfers) during the year was 2,533.

10 years was 3.8 (1960), 3.7, 3.3, 2.7, 2.8, 2.6, 2.2, 3.0, 3.9, 2.9.
The adjusted birth rate, calculated on the estimated population of
177,760 is 14.25 per 1,000.
