Abstract: Electricity power is the most frequently used secondary energy and the most population / household-related energy in human societies. The age and gender structure of population in Chinese households have changed to be much more diversified，which would have a significant impact on the residential electricity consumption at the household level. In order to examine the age-gender pattern in household electricity consumption，we use pooled data from the CFPS baseline database which includes age and gender of all the household members，decomposing household-level electricity consumption into individual-level age-gender pattern by defining the age-gender index as a key variable in the regression model. The results indicate that the impact of household size on per capital electricity usage differs between age-gender population groups. The age pattern presents a"inverted U”shape，while the gender pattern is“higher for females than males". 25-34 year old female population，which has a positive effect on per capital electricity usage，is the most important subject in household electricity consumption. Making and adjusting policy of multistep electricity price and prediction and planning of residential electricity consumption should take age and gender structure of population in households into consideration.
