Yippie, it's math time
Per Wikipedia the 2016 numbers for TV are 1700 residents per square mile. One square mile is 640 acres, so rounding off, about 2.7 residents per acre. There are 1.9 residents per household

My house is on 0.2 acres of land, or 0.1 acres per resident. If there were no streets or rec centers or golf courses or trails or... that density of 0.1 acres per person gives 10 persons per acre

Fenney is to have 14000 homes = 26000 residents on 8000 acres or 3.3 residents per acre

S. Oaks is proposed to have 20,300 homes = 38000 residents on 4518 acres or 8.5 residents per acre.

Something is missing either in my math, or in the new development. Perhaps no golf courses? There are going to be three times as many people per acre in the new development. I can only hope the numbers in the online news are wrong and that the acres are not really 4518. At least on the map shown it looks bigger than Fenney which is said to have 8000 acres.
*************
edit; okay I may have misinterpreted the numbers in the online news story
Perhaps the sentence "The Villages announced the purchase of 8,000 acres near the turnpike which could accommodate 14,000 homes. But the proposed Wildwood ordinance would permit 20,300 homes on 4,518 acres of the property." should be interpreted differently..

That this new area, Southern Oaks, is an area of 8000 acres and that of that 8000 this announcement concerns 4518 acres on which these 14000 homes are being built. And that the remaining 3482 acres will have 6300 homes, giving the total of 20,300 homes. So revise my math to 38,000 residents on 8000 acres which gives 4.75 residents per acre. And delete all figures for Fenney as I erred in thinking the 8000 acre area referred to in the online news meant Fenney.
Corrected Fenney numbers seem to be 3000 homes on 1047 acres or 5.4 residents per acre. So both new developments are significantly more densely populated than the contiguous villages.
