Biden conducted far fewer interviews during his first months in office than Trump did: nine in his first hundred days, compared with fifty-one for Trump and forty-six for Barack Obama. The press has gotten the briefing back, yes, but we’ve lost privileged glimpses into the West Wing. [...]
The WHCA has chided the president for holding fewer press conferences than his predecessors.
Are those stats (for the 100 days) accurate and did the same pattern continue in the subsequent months?
There aren't numbers for the first 100 days AFAIK, but The American Presidency Project has a feature that tracks these numbers by year, dating back to President Calvin Coolidge.
President Biden has held less formal news conferences in his first year as compared to past Presidents. However, these numbers exclude impromptu interactions with the press which was largely popularised by President Trump.
