This shows that the medium and main age range is within the working age gap of 15 to 65 year olds. As you can see, the percentage of people in this age band is 66.5%. This means that at the moment, we have enough contributions to the economy to allow the remaining 33.5% of the population to be catered for significantly.
The industrial revolution saw masses of people moving into cities and towns. And in doing so, moving away from the countryside and rural areas. Now people are moving out of towns into the countryside, and commuter towns etc., because most people these days have access to cars, and other means of speedy transport, i.e. trains and busses.
There has also been a rise since the 1950's onwards, due to the construction of large amounts of high rise buildings and as the Americans call them, “Condos,” which mean there are a lot more people concentrated in one small area on top of one another, many more than before. This leads to a higher population density within a given area in heavily compacted cities. This is typical of places like London where the population density is a lot more heavily compacted than somewhere like Ware in Hertfordshire, where the population density is much less per km2.
During the more recent years, the population has progressively moved south due to the de-industrialization of the North of England, for example Liverpool was an important docks, but they are now obsolete, whereas the South is where all the money and the good jobs are now.
The poorest parts of the UK in terms of wealth are the South West and the North East. There isn't much industry other than tourism in Devon and Cornwall and the North East has been badly affected by the decline of industry. This has led to a large number of people moving to places where they can access the business of the towns more.
