Add valuesets for family income #27
Description
@claude create a Family Income valueset. Check that a family-income valueset does not already exist in the linkml/valuesets repo.
Use commonly observed U.S. income brackets from ACS/BRFSS/NHANES/NIH CDEs, such as:
Less than $10,000
$10,000–$19,999
$20,000–$24,999
$25,000–$29,999
$30,000–$34,999
$35,000–$49,999
$50,000–$74,999
$75,000–$99,999
$100,000–$149,999
$150,000 or more

Don’t know
Consider whether the valueset should:
- Be year-versioned (income brackets shift with inflation), and
- Support multiple levels of granularity (fine vs. coarse bins).
