were there hundreds of thousands of patients in us mental hospitals around 1930?
“they can't treat that many patients a few thousand when there are hundreds of thousands in the hospitals”

first, the part that holds
the speaker is right. around 1930, us mental hospitals held a few hundred thousand patients. the census bureau's own series puts it at about 353,000 at the end of 1931 and about 445,000 by 1940.
what we found when we went and looked
we went to the census bureau's historical statistics of the united states (series b 423–427, patients in mental hospitals). it counts 268,000 resident patients in 1923, 353,000 at the end of 1931 (332,000 of them in state and county hospitals) and 395,000 in 1933. a separate american medical association series in the same chapter (b 375) shows a daily average in mental hospitals of roughly 400,000 around 1930. that is our reading of a scanned table, so treat the exact digits loosely. a peer-reviewed history puts state and county hospitals at 445,000 by 1940 and says the psychiatric profession numbered 2,295 before world war ii. so "hundreds of thousands of patients" against "a few thousand" clinicians matches the record.
assertion by assertion
| assertion | verdict | what the record says |
|---|---|---|
| around 1930 there were hundreds of thousands of patients in us mental hospitals | confirmed | census bureau series b 423: 353,000 resident patients at the end of 1931 (rate 284 per 100,000), 268,000 in 1923, 395,000 in 1933. there is no row for 1930 itself in this table, so 1930 falls between the 1923 and 1931 counts. the census notes that how completely hospitals reported varies from year to year. [1] |
| the hospital population was large and growing through this period, not a one-year blip | confirmed | state and county mental hospitals grew from 150,000 around 1900 to 445,000 in 1940 and stayed above half a million in 1960. a second review describes a 240 percent rise in admissions to state hospitals from 1903 to the mid-20th century. [2][3] |
| only a few thousand clinicians were available to treat them | confirmed | the psychiatric profession numbered 2,295 before world war ii and almost 5,000 by its end. the quote doesn't say which clinicians it means, so we matched it to psychiatrists. psychoanalysts alone were far fewer. [2] |
both directions
for the speaker: every primary count near 1930 lands in the hundreds of thousands. the census bureau gives 353,000 at the end of 1931 and 395,000 in 1933, and its series rises every year from 1931 to 1940. the american medical association hospital series in the same chapter gives a daily average in mental hospitals of roughly 400,000 around 1930. against that, the whole psychiatric profession was about 2,300 people before the war. the speaker's contrast between "a few thousand" and "hundreds of thousands" holds even with generous rounding.
against: little cuts against the claim. the census table has no 1930 row: the nearest counts are 268,000 in 1923 and 353,000 at the end of 1931. that still leaves 1930 well inside "hundreds of thousands," but the speaker gave no source and no exact figure. the claim sentence says "north american (us)". the figures here are us only. canadian hospitals would raise the total a little but change nothing.
what this cannot say
the census figures come from hospitals reporting in, and the bureau warns that completeness varied from year to year. early counts may run low, which would only help the claim. we read the census table from a scanned 1975 pdf. the 1931 and 1933 values are clear. our approximate reading of the american medical association's 1930 daily average is not. "a few thousand" in the quote does not say which clinicians, so our match to the count of psychiatrists is an interpretation. counting patients in the hospitals says nothing about the treatment they got or how they did.
