Answer :
Ravenstein's theory of migration indicates that long-distance migrants tend to move to major cities and economic factors are the primary reason for migration.
It does not state that most people migrate long distances, nor that urban residents are more migratory than rural residents.
Parts of Ravenstein's theory of migration that apply include that long-distance migrants tend to move to major cities, and economic factors are the main reason for migration.
However, the statement that 'most move only a long distance' is incorrect, as Ravenstein stated that most people move only a short distance. Also, the statement 'urban residents are more migratory than those in rural areas' is the opposite of what Ravenstein found; he stated that rural residents are more migratory than those in towns.
