The mid-1999 United Kingdom population is estimated at 59,500,900, a

rise of 2.9 per cent since mid-1991 according to new data released by

National Statistics today. The mid-1999 UK population is 0.4 per

cent higher than in mid-1998 when the population was estimated at

59,236,500. The largest rise was seen in the 85 and over age group

which increased by 27.3 per cent between 1991 and 1999. Although the

United Kingdom population increased overall, there were decreases in

some age groups. The largest decrease occurred in the number of

people aged 16-29. This group was estimated at 10,733,500 in 1999

which is a fall of 13.1 per cent since 1991.

Changes in the population age structure mid-1991 to mid-1999. Table A

shows for various age groups how the size of the United Kingdom

population has changed between mid-1991 and mid-1999. The population

has increased since 1991 with the biggest increases being observed in

three age groups:

- The working population of age 30 and over

- Children aged 5-15

- the very elderly age group of 85 and over

The working population aged 30 and over has increased by 12.1 per

cent since 1991. This increase is due to the post second world war

baby boom and to the high birth rates during the sixties. The very

elderly age group of 85 and over has increased by 27.3 per cent since

1991. This is due to an increased life expectancy.

Despite the overall increase in the population some age groups have

decreased since 1991:

- The working population of 16-29

- Children aged 0-4

- the early retired age group of 65/60-74

The decline since 1991 in the 16-29 age group is mainly as a result

of low fertility rates during the seventies. The decline since 1991

in the early retired age group of 65/60-74 years old is mainly a

result of low birth rates during the thirties.

Components of population change mid-1991 to mid-1999 Table B shows

components of population change in the United Kingdom between

mid-1991 and mid-1999. Of the total increase between mid-1998 and

mid-1999, 76,000 is due to natural change (more births than deaths).

The remainder, 188,400, is estimated to be mainly due to people

migrating to the United Kingdom and this includes people returning to

the United Kingdom after a stay abroad of a year or more.

Table 1 gives the estimated population by single year of age and sex

for the United Kingdom. Further tables by single year of age and sex

for the constituent countries of the United Kingdom and for Great
