The UK’s population increased by 408,000 in 2008, according to the Office for National Statistics (ONS). This is the biggest rise in almost 50 years.
The population boom is the largest recorded since 1962, which saw the numbers rise by 484,000.
The results mean that for the first time in nearly a decade, natural changes to population, such as birth rates and deaths, have overtaken immigration as the biggest factor impacting on population growth.
The ONS believe that the rise has been driven by increased fertility rates and possibly the recession.
Further results showed there are a record 1.3 million people aged over 85, making up 2% of the total population. A massive 791,000 babies were born in 2008, an increase of 33,000 from 2007. The population is steadily growing by 0.7% a year, more than double the rate in the 1990s and triple rate of the 1980s.
The largest ever population increase was recorded in 1947, when a post-war baby boom resulted in a rise of 551,000.
