TITLE: The Number of Undocumented Immigrants in the United States

ABSTRACT:

We apply standard operational principles of inflows and outflows to estimate the number of undocumented immigrants in the United States, using the best available data, including some that has only recently become available. We generate a lower bound for the number of undocumented immigrants using conservative parameter values that underestimate inflows and overestimate outflows. Our lower bound is close to 17 million, 50% higher than the most prominent current estimate of 11.3 million, which is based on survey data and thus different sources and methods. Standard parameter values generate an estimate of 22.8 million undocumented immigrants, twice as large as the current estimate.

This news seems rather timely.

Shouldn’t the United States government know how many people are living in the United States?

Knowing how many people live in your country is something that governments have undertaken to find out for over two thousand years. There are at least three censuses mentioned in the Bible, two in the Old Testament. For the U.S. government to not know within an 8 digit number, because illegal aliens are considered sacred and mysterious, is nuts.
