Hi,
I'm using 3 rounds of cross sectional NSSO data and would like to generate a pseudo panel dataset so I can apply panel data methods.

First I generated a year variable for 3 rounds of data- 68,66 and 61
68- gen year=2011
66- gen year=2009
61- gen year=2005

gen birthyr= year-age

This is the range of birthyr for each round
68- 1915-2006
66- 1904- 2004
61- 1905- 2005

I would like to create 10 birth cohorts [ 1905-1915, 1915-1925, 1925-1935, 1935-1945, 1945-1955, 1955-1965, 1965-1975, 1975-1985, 1985-1995, 1995-2005]

What is the stata code for creating 10 birth cohorts?

Thank you for your help,
Samira.
