Where in law is there a right for a person/institution/business to know who is accessing their "data"?

Trump Is Claiming Mortgage Fraud to Attack Enemies. Is Your Information Public?

The data community needs to weigh in here, not just on โ€œprivacy,โ€ but on data โ€œstewardship,โ€ the way data curators see their ethical responsibilities. The administration has a completely different understanding, namely that all โ€œdataโ€ is fair game for their agenda.

More tinkering: When to report. Who does what, BLS or Census Bureau. What about private sector surveys? What else could one use to measure unemployment, a new question once the Social Security Act [1935] authorized unemployment โ€œinsurance.โ€
More to come...

The โ€œCurrent Population Surveyโ€ was born and has been around ever since. We have a โ€œdata seriesโ€!

4. Get the tabulation report out fast, preferably 2-3 weeks after the data collection.
5.Whoโ€™s going to pay for it? For ~10 years, a government โ€œexperiment,โ€ originally the โ€œmonthly report on the labor force,โ€ late 1930s-1940s, to work out kinks. [Skipping WWII here, a big part of the story.]

3. Letโ€™s get the definition straight: a person was only unemployed if in the right demographic [not too old, not too young], and actually looking for work the week the sample surveyors came around.

2. Probability sampling [a hot new thing at the time], would permit frequent simple measurement [monthly!], so weโ€™ll need a staff of โ€œfield interviewers.โ€

1. Unemployment fluctuates a lot with the cycles of the larger economy, and needs frequent measurement. A census is the wrong instrument to measure it. Too expensive, too slow for the reporting.....

The โ€œdataโ€ were unsatisfactory, irregularly reported, long story short, the Depression accelerated technical work on the issue. [A truncated version of the issuesโ€ฆ]

IPUMS USA: descr: MOUNEMP

A question for the โ€œoccupiedโ€ population went on the 1880 census, usa.ipums.org/usa-action/v..., asking the โ€œnumber of months this person has been unemployed during the census year.โ€ Stayed with changes until 1930 census, including a Congressionally mandated โ€œunemployment censusโ€ in 1930 and 1931.

Unemployment, labor force participation, is hard to measure.

Who does it apply to? Adults? Of what ages? People with their own โ€œbusinessesโ€? What about farmers? What about โ€œhomemakers?โ€ ....

A series of posts on the history of data.
Like the bridges and roads one drives on, one doesnโ€™t need to know about the bridge builder, unless the bridge falls down, fails. Then all of a sudden itโ€™s really important, which is what happened Friday August 1, 2025, with the monthly unemployment report.

Data series, like the unemployment rate, or the consumer price index, are โ€œinfrastructureโ€ โ€“ need to be โ€œbuilt,โ€ engineered, โ€œusable,โ€ are the work of many hands, built over time, generate debate and commentary about how to build, which allows historians like me to report on the building process....
