The sentence that would benefit the most from a revision to a more informal voice is:
"Public transit use seems to be tied to money—the top six areas for venture capital investment were also the top six areas for increases in public transit use."
This sentence could be made more relatable and conversational by simplifying the language and structure. For example:
"It looks like using public transit is all about the money; the places that got the most venture capital also saw the biggest jumps in public transit use."
