Abstract

An overlay having a window frame includes a block of questions positioned to be lined up with an empty space on a census directory. Answers to the survey questions are written in the empty space on the census directory in the window frame. The method of this invention is well suited for taking political surveys using registered voters' lists by placing the overlay on the voters' list and moving it down the series of names on the list and recording the answers to the survey questions as they are provided.
