The gravity model of migration is therefore based upon the idea that as the importance of one or both of the location increases, there will also be an increase in movement between them. Shows the … When used geographically, the words 'bodies' and 'masses' are replaced by 'locations' and 'importance' respectively, where importance can be measured in terms of population numbers, gross domestic product, or other appropriate variables. The larger the cities, the stronger the interaction, and the farther the cities are from one another, the weaker the interaction is, with this magnitude being squared. They also state that the gravity model is an unfair method of predicting movement because its biased toward historic ties and toward the largest population centers. The AP Human Geography course is designed to provide college level instruction on the patterns and processes that impact the way humans understand, use, and change Earth's surface. Population Policies – pro-natal and anti-natal policies, case studies from China, India, Japan and Indonesia; Migration – internal, external, forced and reasons for migration Newton’s Law is applied to urban geography in the sense that it determines the strength of the interaction between two urban geographical regions, which can be cities, metropolitan areas, countries, etc. The first is that people argue whether, for the distance term, to use the actual geographic distance between two places or to use what is known as the functional distance, which refers to the distance by way of roads, rail, or flights. Opponents of the gravity model explain that it can not be confirmed scientifically, that it's only based on observation. To explain the mathematical relationship, it is the strength of the interaction between two cities (we will assume they are cities for the sake of simplicity for this article, although you should still keep in mind that it could refer to any political or geographical subdivision) is determined by multiplying the population of one city by the population of the second, dividing by the square of the distance between the two cities.

The strength of this interaction can be calculated by the formula below: S=frac { { P }_{ 1 }{ P }_{ 2 } }{ { D }^{ 2 } }. This shows that although the population of cities determines how important a city is, regarding its push-pull factors and its interaction strength with another city, it is not as strong a factor as the distance is (hence it being squared). The Gravity Model is a model used to estimate the amount of interaction between two cities. 20 Qs . Long is Long! AP Human Geography Models & Theories. While the gravity model gives a good understanding of the relationship between the two cities and how easily flow occurs between them, there are several weaknesses to the model. Gravity Model says-Distance and population size effect receiving and sending countries -people will travel closer than far but large populations send more people. Critical to human geography is the human population. This is just to show the implications of the model. These various types of flow could be of people, information, commodities, money, labor, and pretty much anything else that moves between two locations. The strength of the interaction between the two cities determines flow between the two cities.
