The RED BLOCK shows the phenomenal population growth being fueled by the federal government's immigration policies. The red represents all the immigrants (above the replacement level of 222,000) who have arrived -- or are projected to arrive -- since 1970, plus their descendants, minus deaths.

The GREEN BLOCK represents U.S. population growth due to the descendants of 1970-stock Americans. It assumes that these "old-stock" Americans will continue their present fertility and mortality rates. There were 203 million people living in the U.S. in 1970. Births to that population have exceeded their deaths, resulting in the growth illustrated in the green block. But the below-replacement-level fertility of "old-stock" Americans will allow this group to stabilize in size soon after the Baby Boomers' children finish having babies. (The Green Block also accounts for replacement-level immigration, which the Census Bureau currently estimates at 222,000 a year.)

Without the radical increase in the numbers of immigrants coming to the United States since 1970, U.S. population would almost be stabilized by now and would peak in 2020 at 255 million (52 million higher than in 1970).

The TOP LINE of the chart represents the actual U.S. population growth between 1970 and now, and is a projection of what the growth will be between now and the year 2050 if fertility, mortality and immigration rates remain similar to those of today. The additional 200 million people will cause a doubling of the U.S. population of 1970 -- a time when most Americans believed the country already had enough congestion and sprawl.

Of the 120 million people who will be added to the United States over the next five decades, 100% are represented in the RED BLOCK on the chart above.

To find similar population growth in foreign countries, we must look to the Third World.

Nearly every other advanced country in the world is moving quickly toward a stabilized population -- or already has achieved it. But Congress each year endorses immigration numbers that force the United States to deal with many of the same problems of rampant population growth that plague the world's poorest countries.

The Future Shown in the Chart Above Is a Future that Does NOT Have To Happen.

Congress Can Change that Future Quickly and Easily.
