Household projection research outputs

Outputs and accompanying technical note to illustrate differences between DCLG's 2014-based and ONS's 2016 based household projection methodology. The GLA 2016-based household projections were published in July 2017. These made use of the an approach based on the 2014-based DCLG household projection model to convert the GLA 2016-based central trend population projection into households. Those projections remain the offical GLA 2016-based household projections. In September 2018 ONS released their 2016-based household projections based on a new methodology. The outputs published here were produced by applying the new ONS household model to the GLA 2016-based central trend population projection. These projections are provided for information and comparison purposes only and do not supersede or replace the existing GLA 2016-based household projections.用于展示社区与地方政府部（Department for Communities and Local Government, DCLG）2014年版与英国国家统计局（Office for National Statistics, ONS）2016年版家庭人口预测方法差异的输出结果及配套技术说明。 基于大伦敦政府（Greater London Authority, GLA）2016年版的家庭人口预测成果于2017年7月正式发布。该成果采用基于DCLG 2014年版家庭人口预测模型的方法，将GLA 2016年版中心趋势人口预测结果转换为家庭户数。 上述预测仍为官方正式的GLA 2016年版家庭人口预测成果。 2018年9月，ONS发布了基于全新预测方法的2016年版家庭人口预测成果。本次公布的输出结果，正是通过将ONS新版家庭人口预测模型应用于GLA 2016年版中心趋势人口预测结果生成的。 本次发布的预测结果仅用于参考与对比用途，不替代或取代现有GLA 2016年版家庭人口预测成果。
