through household survey. ICE抓的這麽勤，哪個村的無證移民還敢上報啊？嗬嗬。

U.S. employment growth counts undocumented immigrants indirectly through the Bureau of Labor Statistics (BLS) household surveys, though they are not explicitly identified by legal status in the data. [1]

The Content of the Letter

The letter is addressed generally to "Dear Resident" because the government selects physical addresses out of a master registry, not specific names. An Official Census Bureau Advance Letter explicitly details: [1, 2, 3]

• That the home has been selected as part of a scientific sample.
• That the survey answers directly calculate the national unemployment rate and help guide Federal Reserve decisions.
• Strict legal confidentiality guarantees under Title 13 of the U.S. Code.
• Clear instructions stating no immediate action is required. [1, 2, 3]

就是底下這種官方“人口調查”的letter。你要是非法移民家庭這種信送到你家郵箱，第一反應是老實上報還是選擇隱瞞/謊報？
