Social Mobility is a measure of change in social status. When an individual shifts from one social setting to another, some social mobility always happens. Actions like migration, marriage, education, employment etc lead to social mobility. However, it is not same as other similar sounding concepts like socio-economic development, GDP growth etc. Social mobility is always a measure of individual (or a small group placed in a similar situation) upliftment. Others are generally collective indicators. A fast growing economy may still have millions of poor. In India also, a section of population had been less socially mobile than others. When benefits of development are reaped unequally, differential mobility is witnessed. The fact that we still have a quarter of population below poverty is a reflection of that.
