Joe Guzzardi: Doubters Challenge Report About Illegal Immigration

“The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990 to 2016," a new study published in the peer-reviewed science journal, PLOS ONE, found that the illegal immigration population in the United States has been, for years, dramatically underestimated.

Using “standard demographic principles of inflow and outflow” and applying the best available and newest data for the period studied, authors Mohammad Fazel-Zarandi, Jonathan Feinstein and Edward Kaplan of Yale School of Management, arrived at a conservative estimate of 16.7 million illegal immigrants in the United States for 2016, and a mean estimate of 22.1 million.

The study, which put the illegal immigrant population at roughly 50 percent to 100 percent higher than the frequently referenced 11 million estimate, stunned immigration think tanks.

The Migration Policy Institute and others questioned how the Census Bureau, the American Community Survey and the National Center for Health Statistics could have overlooked some 11 million illegal immigrants in their population estimates.

As MPI put it, “people leave footprints.”

To grassroots immigration skeptics, however, the study’s findings are consistent with their own informal, from-the-front observations. How, immigration critics wonder, could the illegal alien population remain fixed for years at roughly 11 million?

The static number certainly seems questionable, given that for decades Republican and Democratic administrations alike have tolerated loose borders, endorsed catch and release, and discouraged interior enforcement.

Whether the illegal immigration population is 11 million, 22 million, somewhere in between or even more, the large number of additional people has a direct effect on U.S. jobs and, rarely discussed, the fragile American environment.

Illegal immigrants, we are often told, come to the United States in pursuit of a better life. That generally means adopting an American lifestyle, which is highly consumptive.

More people in the United States means more consumption and more development. Natural habitat is increasingly lost for more housing, highways, schools, hospitals, stores, restaurants, offices, roads, parking, waste and all the other infrastructure needed by ever-more people.

Ultimately, more growth in America means more sprawl and less open space, which means less biodiversity.

Since the first Earth Day in 1970, celebrated during President Richard Nixon’s first term, the U.S. population has increased to nearly 329 million from 203 million. Looking ahead, the Pew Research Center projects that the U.S. population will reach 441 million by 2065, 88 percent fueled by immigration and births to immigrants.

Two Oregon State University scholars, Paul Murtaugh and Michael Schlax, co-authored a groundbreaking study, “Reproduction and the Carbon Legacies of Individuals,” that added an important perspective to the immigration debate.

According to the research of Murtaugh and Schlax, the average carbon footprint of a Mexico resident is 3.67 tons per year; in the United States, it’s 20.18 tons. Approximately 5.6 million Mexican illegal immigrants currently reside in the United States. If humans are indeed the major climate change driver, then logic dictates the solution is fewer people in a country with a high carbon footprint and not more.

The Murtaugh-Schlax study demonstrated that a family choosing to reduce the number of children by one could achieve a lifetime CO2 emissions savings of 9,441 metric tons. Contrast this to that same family electing to increase their car's fuel economy to 30 from 20 mpg. Improving mpg would result in a savings of only 148 metric tons.

It should be obvious that no amount of recycling, energy efficiency or smart growth will restore America to a sound, sustainable place environmentally.

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
