The investigation only covered patients newly notified
or transferring into the borough from other areas. The total
of four hundred and two cases surveyed differs from the total
of tuberculous patients visited in the year in so far as the
difference consisted of old cases changing residence within
the borough.
In 1951, a full survey was not made, but it was estimated
that 20% of the tuberculous patients visited for the first
time in that year were immigrants who contracted the disease
within ten years of arrival in this country. A more accurate
investigation showed that the proportion for 1952 was 16%,
whilst the comparable figure for 1953 was 10%. Persons born
in the Republic of Ireland were regarded as immigrants for
this purpose.
The publication of the findings of the 1951 Census
enables the problem of immigrants to be put into proper
perspective. The Kensington Census figures show that out of
a total population of 168,160, there were 29,353 residents
(or just over 17%) who were born outside the United Kingdom
and the Republic of Ireland.
Tuberculosis - Notifications and Mortality
Notifications and deaths from tuberculosis are increasingly
occurring at a later age, particularly amongst males. This is
illustrated in the following table which shows Kensington
notifications and deaths for two five-year periods separated
by a gap of twenty years. The table, which is shown graphically
in Chart 1 on page 64, shows the figures of males and females
in age groups.
