Changes in the age of New Zealand farmers: Problems for the future?

Earlier research shows that between 1971 and 1981, the number of farmers in New Zealand increased and their average age decreased, whereas between 1981 and 1991, the opposite trend occurred. This article addresses the issue of change in the average age of farmers since 1991 using recent census data. It reviews the difficulties in obtaining good data and describes the adjustments need to be made to obtain a consistent data series from 1971 to 2006. The long‐term trend for increasing age of farmers and farm workers continues. This demographic aspect of farm structural change is then discussed in terms of the sustainability of farming by reference to productivity and potential problems with succession.
