New form looks like this:
Interesting addition: "Not Hispanic or Latino".
The distinction is valid when the checkbox says "white" for race. The criminal statistics for hispanic and non-hispanic whites where lumped together for a long time. That diluted the contribution that hispanic whites where making to criminal activity. It is larger than non-hispanic whites and swamped by the proportions. The aim is to identify criminal activity from the white hispanics where a large proportion are illegal aliens. The difference was significant and has been retained as part of the incident reporting systems used by law enforcement. Seeing this on the Form 4473 is no surprise. It is consistent with other record keeping categories.
