Not distance)Threshold - minimum number of people (customers) needed to sustain a business (viable) Developers of shopping malls, department stores, and large supermarkets typically count only higher-income people.Reasons why a threshold could dropA drop in populationChange in cultureIntroduction of substitutes Breaking Point - line where customers will choose to go to another business for a service/goodLow order goods – necessities – cheap products that are purchased frequently (low range and low threshold)High order goods - luxuries – not essential and are purchased infrequently (high range and high threshold)An example of a low order good would be Walmart. Walmart sells groceries that people need and purchase often.An example of a high order good would be BMW car dealership. Cars are a luxury and are not purchased often.Small settlements, such as hamlets, would have few low order goods. Larger settlements, such as a city, would have more low order goods and high order goods.Central Place TheoryCentral Place Theory attempts to explain the pattern of settlements & Urban Hierarchy = HamletVillageTownCityMega cityWorld cityCities are economic hubs because diverse services & goods are not available in smaller settlementsCentral Places compete with each other for services & goods Thus, larger the city, greater the distance between it & its rivals915035151765COLOR TIME!!!!Central Place TheoryWhy do we not ever see a perfect central place hierarchy?Physical geography is important!
