What it means
Population sets the number of potential customers, workers and households a market has. Faster-growing states add demand for housing, schools, health care, transport and everyday goods each year, while states with slower growth and older populations shift demand towards health care, convenience and services. A higher urban share usually means higher spending per person, but also higher rents and more competition.

About this statistic
These are the official projections of India's Technical Group on Population Projections, which carries the 2011 Census forward using birth, death and migration rates for each state. They are the figures government departments use for planning until the next census results are published.
Population tells you how many potential customers a state has and how fast that number is changing; the urban share shows how many of them live in towns and cities, where spending, competition and business costs are all higher.
