Significant changes are occurring in the population composition in terms of age. The most notable change however is the increase in the number of the aging population in the U.K. in 1911 the population of older people of about 65 years and above stood at 5% of the total population (Bartlett & Philips, 1995). This figure has risen steadily over time. By 1971 it was 14% and 15.7% in 1991 about the time the European Union was formed. This percentage occupied by this population is expected to reach 24% by 2015. Statistical this population has been fair till 2001 and it is rising at a rate of 5% annually. The rate is expected to prevail for several decades.
In these changes old people of about 65-79 will represent about 12% of the whole population while those above 80 years of age will be about 2-4%. Currently the U.K population can be characterized by three large age groups. The first one is that which was born during the post world war II periods baby boom between 1946 and 1951. The second and largest is the group is the product of a baby boom between 1961 and 1966.
There was also another baby boom which occurred between 1986 and 1991. These groups consist of the largest number of U. K population. Within the country, the population is not evenly distributed and some areas have large numbers of children and young adults while other has large numbers of adults and the elderly. In the U.K. the children between 0-14 years represent 18% of the total population, 15-64% 66.3% and 65 and above represent 15.7%. This certainly indicates that the U.K population is increasingly become aged.
