§ Mr. Powellasked the Secretary of State for Social Services what estimates of births and deaths, respectively, produce the estimated current annual natural increase of rather under 30,000 in the number of people in Great Britain who were born in the New Commonwealth, together with their children born in Great Britain but excluding people of United Kingdom descent born in the New Commonwealth.
§ Mr. CrossmanThe Registrar General estimates that the number of births to this population may currently be a little under 35,000 per annum, while the number of deaths is probably of the order of 5,000 per annum. These estimates reflect the bias in the age structure of this population towards the young adult and child age groups shown by the 1966 Sample Census of Population, which results in a high crude birth rate and low crude death rate.
The fertility assumption is that age specific female fertility averages one third higher than the national rate. The mortality assumption is that mortality at any specific age is the same as the national average.
