The Kish grid or Kish selection grid is a method for selecting members within a household to be interviewed. It uses a pre-assigned table of random numbers to find the person to be interviewed. It was developed by statistician Leslie Kish in 1949.
It is a technique widely used in survey research. However, in telephone surveys, the next-birthday method is sometimes preferred to the Kish grid.
