The graph below shows the growth of SEWA as a national union.

For more than 4 decades, SEWA’s growth in membership and geographies is increasing organically based on the needs and demands from the members.

While the overall trend has been upward, there have been periods of fluctuation over the past decade. Membership increases occurred as a result of campaigns which developed into mass movements in some rural districts, concrete gains from organising of some categories of workers like vendors and home based workers and also because of support during crises.
