NumbersUSA (NUSA) seeks to grade all Congressional actions since 1989 that affected -- or would have affected -- the numerical level of immigration and illegal migration into the U.S.
Actions are weighted based on the best available assessment of their impact or potential impact on the size of the U.S. population.
NUSA includes not only floor votes but also committee votes, co-sponsorships and other leadership actions such as signing a letter in support of or against particular immigration legislation.
NUSA's grades are based on a systematic, consistent set of principles that have been evaluated and reviewed by experts in immigration policy (including people from the State Department, Immigration and Naturalization Service, U.S. Commission on Immigration Reform, Census Bureau, congressional immigration committee staff, Members of Congress, several think tanks of differing immigration philosophies and a number of universities).
Unlike many congressional scorecards, the NUSA grading system does not pick and choose among actions in a way to skew toward a particular party or particular members. The grades are based on whether actions raised or lowered immigration numbers and don't necessarily reflect what NUSA's preference was. While it is not possible to construct a purely objective rating system, NUSA has attempted to be as honest and accurate as possible in reflecting the purely numerical effects of immigration actions. We believe that those people who support high immigration and high population growth would find our scoring so reliable that they could interpret our F- grades as A+ grades for their side.
Following is a guide to the way in which NUSA's Congressional Report Cards grades are calculated. If you have questions about the weighting of a particular action or any other scoring matter, please contact us.
| Total Possible Points | |||||
| Subject | Immigration Reduction Percentage | Weight for Subject | Points for Immigration Reduction | ||
| Reduce Illegal Immigration | 100 | X | 2.75 | = | 275 |
| Reduce Chain Migration | 100 | X | 2.25 | = | 225 |
| Reduce Anchor Baby Citizenship | 100 | X | 1.70 | = | 170 |
| Reduce Amnesties | 100 | X | 1.00 | = | 100 |
| Reduce Worker Importation | 100 | X | 1.00 | = | 100 |
| Reduce Refugee/Asylum Fraud | 100 | X | 0.80 | = | 80 |
| Reduce Lottery | 100 | X | 0.50 | = | 50 |

If amendments to immigration bills have no clear numeric effect, they will be scored in this way: Count the total number of amendments that are being scored, and increase the total by one. Then divide that number into the total points assigned for the final committee or floor vote.
This is designed to keep somewhat ambiguous votes on amendments from having more weight than a final vote or an amendment for which there is a clear numeric effect.
