The Rockefeller Commission recommended that annual immigration be capped at 400,000 per year1 (a minority of the members recommended reducing immigration by 10 percent every year until it was reduced to the 1925-1965 average of 178,000 per year2).
U.S. Population 1969: 202,677,000
Persons obtaining Legal Resident Status (LPR) 1969: 358,5793
The commission concluded:
“After two years of concentrated effort, we have concluded that, in the long run, no substantial benefits will result from further growth of the Nation’s population, rather that the gradual stabilization of our population through voluntary means would contribute significantly to the Nation’s ability to solve its problems. We have looked for, and have not found, any convincing economic argument for continued population growth. The health of our country does not depend on it, nor does the vitality of business nor the welfare of the average person.”
The recommendations by the Select Commission on Immigration and Refugee Policy4, chaired by Reverend Theodore Hesburg of Notre Dame University (and previous chair of the U.S. Civil Rights Commission), called for a “sound, coherent [and] responsible immigration and refugee policy” including:
U.S. Population 1978: 222,585,000
Persons obtaining LPR 1978: 589,8105
A quarter of a century ago, national environmental groups – including the Natural Resources Defense Council and the Sierra Club – served on President Clinton’s Task Force on Population and Consumption, which recommended Congress regulate immigration (which was and is projected to drive the majority of future U.S. population growth) to allow for population stabilization6.
“This is a sensitive issue,” they wrote, “but reducing immigration levels is a necessary part of population stabilization and the drive toward sustainability.”
U.S. Population 1993: 258,799,753
Persons obtaining LPR 1978: 903,9167
“As a matter of public debate, immigration is a sensitive and explosive issue, and both legal and illegal immigration must be addressed with great sensitivity and care in order to advance the debate. We acknowledge these impediments to easy and informal dialogue, and we urge that participants take appropriate care so that a reasoned discussion of immigration and the American future can begin. We believe that reducing current immigration levels is a necessary part of working toward sustainability in the United States.”
President’s Council on Sustainable Development, established in 1993 to find ways “to bring people together to meet the needs of the present without jeopardizing the future.”
This bi-partisan commission, chaired by the late Rep. Barbara Jordan (D-Texas), made the most thorough examination of the impact of U.S. immigration policies of any federal commission to date. The final recommendations were presented to Congress and President Clinton in 1997 (more than six years after the commission was formed). Their recommendations to create a “credible, coherent immigrant and immigration policy” and a “credible, efficient naturalization process” included setting an immigration admissions level of 550,000 per year, to be divided as follows8:
U.S. Population 1990: 250,132,000
U.S. Population 1997: 272,912,000
Persons obtaining LPR 1990: 1,535,872
Persons obtaining LPR 1997: 797,8479
