Further evidence of the threat to Britain’s First World status has come with new projections which show that Britain’s population will increase by 24 percent within the next 40 years, mainly due to increased fertility levels amongst immigrants.

The statistics, released by the US-based Population Reference Bureau (PRB), come hard on the heels of UK Communities Department figures which show that a majority of new housing demand in Britain will be from immigrant birth rates.

According to the PRB, Britain's population will increase by 15 million to reach 77 million by 2050. The current UK population, the PRB said, stands at 62.2 million.

This increase, the PRB continued, is at a far faster rate than nearly every other European country and will add numbers equivalent to the combined populations of Glasgow, Birmingham, Manchester, Leeds and Liverpool added to Britain “within two generations.”

According to the figures, based partly on Office for National Statistics (ONS) reports, a large percentage of the increase is due to a spike in births.

According to the figures, immigrant mothers accounted for more than half of the increase in births. The fertility rate among “British-born women also rose sharply” but the data did not take into account how many of these “British-born women” are themselves second or third generation immigrant stock.

Dramatically increased birth rates are a trade mark of the Third World. According to the United Nations Population Division, Third World Nations have a birth rate (calculated as the number of births per 1,000 persons) which dwarf First World reproduction levels.

For example, the UN figures show that African states, such as the Democratic Republic of the Congo, Guinea-Bissau, Liberia and Niger, all have birth rates of 49 per 1,000 persons.

These nations are closely followed by Afghanistan, which has a birth rate of 48 per 1,000 persons, and then other African nations such as Mali (48), Angola (47), Burundi(47), Uganda (46) and Sierra Leone (46).

Pakistan has a birth rate of 27 per 1,000 persons, while India has a birth rate of 23 per 1,000.

Most European countries have a birth rate of below 10, and even that figure is artificially inflated because of Third World immigration.

According to the PRB, the world's population will increase from its current 6.89 billion to 9.49 billion by 2050, with India being responsible for a significant part of this increase, becoming the largest country in the world by overtaking China.

India has a population of 1.19 billion, and is expected to hit 1.75 billion, adding the equivalent of the entire population of the European Union within 40 years.
