The birth rate is higher than the death rate and this has shown a population increase. At the moment the birth rate is falling. This is due to our life styles. Contraception is more widely available, women are putting careers in front of starting a family and there is more awareness of family planning.
The death rate is so low because of new medicine and better health care facilities to look after the elderly. They are living longer due to better sanitation. This stops them from contracting diseases from the sewage systems as well. The elderly that are ill and that can’t look after them selves have the opportunity to go to care homes where they will be looked after.
The cost of living has increased a lot where as wages have not met this demand, therefore people wait until they have got enough money to support the cost of a child, this is why birth rates have fallen.
People are getting married later in life and this effects the birth rate as people want to have children when they are married. They also want longer careers so put this before starting a family and having children.
Some political factors effect the birth rate such as war which created baby booms when the men got back from the battle field. This is why there was such a rise in birth rates in the 1950’s, and that is why at the moment there are more middle aged people around.
This is a strong political factor effecting population change in the UK. A number of middle aged people come into the UK looking for employment, this increases the population of people in their early 20’s-late 30’s. they generally move from countries in eastern Europe. Also there has been an increase in rural to urban migration meaning that the cities have the majority of the population.
