What was one impact of the increased western population on the nation?

Firstly, in the UK, the ratio of people of working age to people over 65 could fall from 3.7 to 1 in 1999 to 2.1 to 1 in 2040. (BBC) This suggests a very big increase in the dependency ratio and is consequently a cause for concern because with current spending pension commitments, it will place a higher burden on the shrinking working population.

However, others argue it is a mistake to base calculations solely on a fixed retirement age of 65. If life expectancy increases dramatically, you would expect a sensible policy is to allow some increase in the retirement age, e.g. keeping the same % of your working life for retirement. The UK government has already made tentative steps to raise the retirement age and increase the role of private sector pensions. These policies will make an ageing population more manageable.

In recent years, the impact of an ageing population in the UK has also been mitigated by a rise in net migration levels. Though with the UK’s exit from the EU, there is an expectation net migration levels will fall. An side-effect of this policy, will be a faster rise in the dependency ratio.

Dakotas, Colorado, and other territories became states.

Explanation:

The population began to increase in western parts of America including Colorado, Dakotas (North and South) and other territories. The migration began to take place after the declaration of the westward expansion in 1803. Majority of the people who moved were the white settlers seeking a place to live to start a new life. The increasing population in the western part led the federal government to bring Colorado in 1876 and Dakotas in 1889 as states under the United States.
