Homes in Decatur
Decatur is a city of houses: of its 36,018 homes, 74% are detached, 3% are townhouses and other attached houses and 21% are apartments or units in buildings of two or more homes.
The biggest building period was 1950 to 1979, which accounts for 47% of homes standing today; 5% are from 2000 or later. The median home dates from 1960. 63% of homes are lived in by their owners.
In nearby Springfield, 38 miles away, 65% of homes were built before 1980, so Decatur's windows are on the whole older. Nationally, Decatur's homes are older than those in 90% of the 881 US cities we have census figures for.

Out-of-square openings
With 79% of homes built before 1980, many openings have had decades to settle. Measure each one's width at the top, middle and bottom, and both diagonals. If the diagonals differ by more than about ¼ inch, add a mounting frame in the designer, or choose an outside mount so the shutter covers the uneven edges.
Plaster walls and deep casings
32% of homes date from before 1950, when walls were plaster on lath and windows sat in deep wood casings. Plaster cracks if you drive screws carelessly: drill a pilot hole, use fixings made for plaster, and fix into the casing or the framing behind it. A deep casing is good news for an inside mount; measure its depth before you choose a louver size.
Replacement windows
47% of homes went up between 1950 and 1979, and most of them have had their original windows replaced since. A replacement window often sits further into or out of the wall than the old one, so the depth you have for an inside mount may differ from window to window in the same house. Measure every opening rather than copying one.
Whole-house orders
With 74% of homes detached, most orders here cover a whole house: bedrooms, a patio door, perhaps a bay. Put every window in one list in the designer so the louver size and colour match from the street, and if you have an HOA, send it the drawings before you order.

Cold winters
With 110 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.
