ANSWER:Physical aspects. Every community has a physical presence of some sort, even if only one building. Most have a geographic area or areas they are either defined by or attached to. It's important to know the community's size and the look and feel of its buildings, its topography (the lay of the land -- the hills, valleys, rivers, roads, and other features you'd find on a map), and each of its neighborhoods. Also important are how various areas of the community differ from one another, and whether your impression is one of clean, well-maintained houses and streets, or one of shabbiness, dirt, and neglect.If the community is one defined by its population, then its physical properties are also defined by the population: where they live, where they gather, the places that are important to them. The characteristics of those places can tell you a great deal about the people who make up the community. Their self-image, many of their attitudes, and their aspirations are often reflected in the places where they choose -- or are forced by circumstance or discrimination -- to live, work, gather, and play.
