Lakeville Lake and Lake George
North and central Addison Township is tract 1203, block group 3. The 2020 to 2024 American Community Survey shows a median owner-occupied value near $517,800, with a margin of about $68,215, a median year built of 1992 and 519 owner-occupied homes.

Round Lake and Yule Road
The southeast block group, tract 1200 block group 2, includes Round Lake and runs near Yule Road. The American Community Survey puts its median owner-occupied value near $380,400, but the margin is very wide, about $200,939, so read it as a rough guide. Median year built is 1990 and the block group holds 473 owner-occupied homes. In 2020 about 311 of its homes were in the Romeo district and about 84 in Oxford Area.
Secord Lake and Mayfield Road
East of Leonard, tract 1200 block group 3 covers Secord Lake and the land near Mayfield Road, and part of the Village of Leonard.

Miller Lake and the southeast corner
The smallest block group, tract 1200 block group 1, is about 1.3 square miles around Miller Lake in the southeast. The Census did not publish a median value for it because the sample is small. It counts 98 housing units, of which about 72 are mobile homes, with a wide margin, and a median year built of 1989. In 2020 about 147 homes were in the Romeo district and 32 in Oxford Area.
Indian Lake and Addison Oaks
The southwest, tract 1203 block group 2, has a median owner-occupied value near $373,500, with a margin of about $60,840, a median year built of 1979 and 334 housing units. Indian Lake falls in ZIP 48370 and Addison Oaks County Park at 1480 West Romeo Road in 48367, so the block group straddles two ZIP codes. In 2020 about 202 homes were in Lake Orion Community Schools and 200 in Oxford Area.
