A New Study from Yale University Indicates there are 22.8 Million Undocumented Immigrants Living in the US
An working paper by Dr. Mohammad Fazel Zarandi from the Yale School of Management, coauthored by two other Yale professors, estimates that there are 22.8 million illegal immigrants in the United States.This is over double estimates compiled by the Department of Homeland Security, which claims 11.1 million illegal aliens live in the US.
The paper’s abstract outlines some of the reasons why their estimate is both higher, and better than the current government statistics:
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.
