Consider searching the web for stats on a health concern. Sometimes it is useful to narrow to government sites with site:.gov. Sometimes you can also use the word stats or statistics to narrow the search.
Example: obesity site:.gov
The first result is from Centers for Disease Control and Prevention (CDC).
Example: "mental health" stats site:.gov
The first result is from the National Institute of Mental Health (NIMH).
Availability of stats depends on what has been collected and how it has been collected. These may or may not cover your group by age, gender, ethnicity, etc.
