100-m resolution Age-Stratified Population Estimation from the 2020 China Census by Township (ASPECT)

Introduction

Gridded population datasets are instrumental for modeling the interactions between human and the environment at fine spatial scales. Here, we introduce an Age-Stratified Population Estimation from the 2020 China Census by Township (ASPECT), estimating total population and population by age groups (0-14, 15-59, 60-64, ≥65 years old) at 100m spatial resolution as of year 2020. We used a dasymetric mapping approach to downscale township-level population data (n=40,718 townships) from the 2020 China Census to 100 by 100 m grid cells. The study area is mainland China.
