How might we know whether a small town is declining or just experiencing change? Here is one suggestion:

The University of Illinois Extension earlier this year held a series of webinars to arm leaders of rural communities with positive data, such as fully occupied homes and anchored schools, while suggesting language those leaders should use to recruit people to move to rural towns, which are often coping with negative stereotypes…
Indeed, residents and leaders in Cullom and Wenona, a town of 1,000 an hour’s drive away and about 25 miles south of the LaSalle-Peru area, say their towns are very much in demand. Cullom Mayor Barbara Hahn said that people — mostly from larger cities around the state — call her “all the time” to see if there are any houses for sale and she mostly has to tell them that the housing stock is at capacity…
But Neste said that the lack of population increase is not because rural life is undesirable…
The circumstances lead to one inescapable, albeit morbid, conclusion, experts say. Prospective rural dwellers are left waiting for seniors occupying single-family homes to die.
What is lurking behind this discussion is an assumption in the United States about communities: they are considered healthiest if they are growing. Communities whose populations are stagnant or declining are often viewed as not doing well. There needs to be construction, population growth, and new businesses in a community for outsiders to suggest that it is doing well. The end of this story above tells of one downstate small town that implemented a TIF district and took on risk in order to build some new housing.
But, not all communities in the United States grow decade after decade. Some are growing now, particularly in the Sunbelt. A number of cities, suburbs, and small towns reached their population peak in the past. Some of these examples are regularly discussed, such as Detroit or Chicago or rural small towns.
The measures suggested above offer some different ways of discussing the vitality of a community. In-demand housing is something Americans understand; if there are few housing units available, this suggests people like the community. Having thriving schools is another aspect Americans like as good schools suggest a community has plenty of children and the community rallies around an institution that can help the next generation succeed.
Other measures that might also be helpful:
-The number of active community groups. This suggests people want to participate.
-The number of local jobs available per resident. Are there economic opportunities in the community?
-The number of local businesses owned by residents or nearby residents. This highlights local business activity compared to national firms (like dollar stores or fast food restaurants).
More broadly, a more open conversation among Americans about what marks a healthy or good or desirable community could provide more measures than just population growth.
