You can try something like this:
=ROWS(FILTER(B11:B9291, T11:T9291=MAXIFS(T11:T9291,G11:G9291,2)))
It doesn't matter which column you use as the first input parameter for FILTER; all that matters is that it have the same form as the second input argument. It presumes that column T in the representation of height. Similar to adding additional limitations to MAXIFS, you can add as many criteria as you like (the only restriction is that it needs to be a range, not an array). For instance, I'm not sure how you can tell if someone is living based on the input data.
You can also use the entire column, if it makes sense for your case. As the following example:
