New England
New England’s population is approximately 14.25 million , this number is growing by roughly 67,890 per year.

186 people per day are added to the regional population. 123 people per day are added from fertility – the net sum of approximately 455 births and 332 deaths . A net 63 people are added from human migration (140 are added from foreign immigration and 77 leave from emigration internal to the US ).

The regional rate of population growth is .4% . In 175 years of growing at such a rate, the regional population will double in size.

The US Census Bureau forecasts that regional growth rates will fall to 0.16% by 2030. However, this is still positive growth and the aggregate annual addition in 2030 would still be 26,294 people added to a existing 15.62 million.

The Census Bureau projects that regional population will increase by 1.37 million by the year 2030. This is a 9.6% increase. It is also a best case scenario – one that assumes rates of fertility, mortality, and migration will hold relatively constant until 2030.

United States
US population in the summer of 2008 is approximately 304 million, this number is growing by roughly 2.4 million per year.

6,580 people per day are added to the US population. 4,630 people per day are added from fertility – approximately 11,330 births and 6,700 deaths . Rough estimates indicate that net 1950 people are added from human migration – approximately 2800 are added via legal immigration and 850 leave via emigration.

The national rate of population growth is .7%. This may not sound significant, but it is. In 100 years of growing at such a rate, the national population will double in size.

US Census Bureau projections indicate that national growth rates will fall to 0.6% by 2050. However, this would still be positive growth and the aggregate annual addition in 2050 would still be 2.7 million people added to an existing 419 million.

The US Census Bureau projects that national population will increase by 115 million by the year 2050. This will be a 37% increase and is the result of increasing fertility rates and steady immigration.

The World
World population in the spring of 2009 is approximately 6.7 billion people. This number is currently growing by roughly 81 million per year.

225,000 people per day are added to the existing global population – this is the net sum of approximately 380,000 births and 155,000 deaths.

The global rate of population growth is 1.15%. This may not sound significant, but it is. In less than 65 years of growing at such a rate, the world population will double in size.

The US Census Bureau forecasts that global growth rates will fall to 0.5% by 2050. However, this would still be positive growth and the aggregate annual addition in 2050 would still be 46 million people added to a existing 9.4 billion.

The United Nations projects that world population will increase by 2.5 billion by the year 2050. This is a best case scenario however, one that assumes dramatic declines in fertility. If fertility rates remain unchanged from today, the world will add about 5 billion people by 2050. That is roughly a 75% increase.
