Measuring Illegal Immigration at US Border Stations by Sampling from a Flow of 500 Million Travelers
نویسنده
چکیده
Five hundred million travelers enter the US yearly at a Port of Entry (POE) after an Immigration & Naturalization Service (INS) interview. We describe a general method for sampling from a flow, and summarize results from random reinspections of travelers at 20 POEs. Analyses reveal that 47 in 5614 travelers (0.8% ± 0.24%) were erroneously granted entry. Results suggest INS intercepts 9.3% to 16.0% of travelers attempting illegal entry at a POE, and that INS mistakenly admits 2.95 to 5.45 million illegal immigrants at POEs annually. Additional applications of our sampling method (e.g., for quality control, population studies) are briefly discussed.
