 | | In selecting houses the interviewer goes to the center of a village, throws a pencil into the air, and walks off in the direction to which the pencil points to the edge of the village counting houses. |
 | | EPI, under conditions of our simulations, will oversample houses that (1) are on less populated roads, paths, (2) houses in the center of the village, (3) houses closely grouped together, (4) houses not far out from the village center, i.e., not at the edge of the village, and (5) houses not isolated. |
