120
(3 females to each male) reflects the normal higher mortality rate
of the males and probably the effect of the 1914-1918 war as well.
Table I gives the composition of the population of the Borough
by age, sex and marital condition in quinary age groups.
Density.—In addition to the density of population by wards
and an indication of the accommodation occupied therein, it will
be observed in Table II that, for the Borough as a whole, the number
of persons per acre was 23.3 a reduction of 2.9 from the 1931 figure.
With exception of the South East, all wards showed a reduction in
density as well as an increase in the dwelling tpace available per
person.
The total dwellings in the Borough numbered 21,712 as compared
with 18,364 in 1931, so that the net effect of all new building,
structural alteration, demolition, war damage and conversion to
other uses during the past twenty years has resulted in an increase
of 3,348 dwellings ; this is equivalent to a rise of 18.2%.
The average number of rooms per structurally separate dwelling
was 4.84 as compared with 5.51 in 1931, a reduction partially
accounted for by the conversion into flats of the larger types of
properties.
Actual households increased by 4.7% from 25,144 to 26,397
and this was due in the main to an advance in the number of 2 and
3-person families.
Housing pressure, measured by the proportion of households to
dwellings, showed that in Greenwich, there was an average of 1.2
families per dwelling each consisting of 3.23 persons. Comparable
figures for 1931 were 1.39 and 3.74 respectively.
Taking into account only private households, there were 1.2
rooms per person, or alternatively 0.83 persons per room, a sign
that sufficient accommodation is available but that it is unevenly
distributed.
Assuming the standard of measuring the state of overcrowding
as being more than 2 persons per roim then the population under
this category has been reduced from 10,428 (11.1%) in 1931, to
1,576 (1.85%) in 1951.
Tables III and IV are designed to show the more direct features
of the housing situation, the actual dwellings available, the number
of rooms therein, the households occupying them and the size of
the households in relation to the rooms occupied.
