In that Korea's rapid social change is related not only to population problems such as low fertility and aging but also to the form and size of households such as family formation and demolition and increase of single households, future household projection are made and published by nationwide and regions along with future population projection. Generally, future household projection estimates the future expected households by reflecting the existing demographic changes and household changes, but rapid changes in population dynamics may result in unrealistic projection in long-term forecasts. This paper develops a new prediction model of headship rate to reflect the overall trend of household change in Korea in making future household projection and to reduce the influence of recent rapid change patterns over time. This paper proposes heuristic Li-Lee model by applying heuristic Lee-Carter model (Cho et al., 2018a), and adding the speed control coefficient to the Li-Lee model. The analysis results of long-term forecasts show that this model is suitable for long-term prediction of headship rate for regional future household projection.
