Migrant workers play an important role in the Tiruppur's economy. This paper explores the factors responsible for getting employment and how it is a source of employment based on the primary data collected from 200 migrant households of Tirupur by using stratified random sampling technique. The structured interview schedule was used to collect the information from the selected households and Garett Ranking Technique was used. The analysis of pull factors shows that continuous employment is the most important pull factor. It is found that relatives and friends are the important source of information for more migrants after getting the assurance of employment. The main reason for the migration is landlessness, indebtedness, family commitment, inadequate income to maintain family, low income from agriculture, failure of crop, low wage, failed of own business, not willing to be an agricultural laborer, family problem and religious/social/political conflicts.
