Distribution of Age Population
Furthermore, UK population growth is being combined with an ageing population. The number of people aged over 65 is set to nearly double between 1971 and 2030. From one perspective, this implies, higher taxes, budget deficits and spending cuts. (Demographic Time Bomb)
But, population growth is not all bad. The UK's population growth, helped by net migration means that the dependency ratio is growing at a much slower rate than EU counterparts such as Italy and Germany who have a falling birth rate. Population growth means an increase in labour force, and productivity. It gives more scope for tax revenue without increasing tax rates.

World Population Growth.
Here's an example of statistics which give different perspective. Firstly, the human population has mushroomed in past few centuries. We have long ago dismissed the 'dismal prophecies of Malthus' who as early as the nineteenth century was predicting the growing population would soon run out of food and starve. But, the increased global population will place a greater strain on the world's supply of commodities and threaten the fragile eco-system. These effects are hard to quantify and it may be the growth in population proves much less sustainable than we would like to believe. But, then hopefully earth may prove more adaptable than we fear. Given the stakes involved, hoping may not be enough.
Forecast for Population Growth.
The good news (that is if you equate good news with a slower population growth) is that the world's population growth is forecast to fall overcoming decades. Of course, the key economic and environmental issues are mainly magnified by population growth. You can damage the environment with a small population. There is no reason why a large population cannot be conscious of global and environmental issues.
