Is there a difference in meaning between these two sentences?

• More people live inside this circle than outside it.
• More people live inside this circle than outside of it.

No, though the second one is slightly more explanatory. As with the old quip (usually credited to Groucho Marx), "Outside of a dog, a book is a man's best friend. Inside of a dog, it's too dark to read." --←Baseball Bugs ^{What's up, Doc?} carrots→ 15:06, 12 January 2022 (UTC)[reply]

There is some doubt that the joke originated with Groucho.^[1] While outside of  is synonymous with the preposition outside, it has a second meaning, which it does not share with outside: "except for", "aside from". The joke exploits this dual meaning.  --Lambiam 15:24, 12 January 2022 (UTC)[reply]

For consistency, you should probably use "of" twice, or omit it twice. --←Baseball Bugs ^{What's up, Doc?} carrots→ 15:48, 12 January 2022 (UTC)[reply]

"Inside of" is possible but not usual, and I wouldn't use it merely for consistency with "outside of". -- Jack of Oz ^{[pleasantries]} 20:53, 12 January 2022 (UTC)[reply]

"Inside of" sounds okay to these Canadian ears (although I prefer the more colourful "innards of", preferably with "outards of"). Clarityfiend (talk) 22:04, 12 January 2022 (UTC)[reply]

Thank you very much, everyone. I'll thus omit of in my redrawing of File:Valeriepieris_Circle.jpg. Cheers, cmɢʟee⎆τaʟκ 01:08, 13 January 2022 (UTC)[reply]
