China, Macao Special Administrative Region - Population Counts

<b>WorldPop produces different types of gridded population count datasets, depending on the methods used and end application. 
Please make sure you have read our <a href="https://www.worldpop.org/methods/populations" target="_blank">Mapping Populations</a> overview page before choosing and downloading a dataset.</b> 
<br/><br/>   
Bespoke methods used to produce datasets for specific individual countries are available through the <b>WorldPop Open Population Repository (WOPR)</b> link below. 
These are 100m resolution gridded population estimates using customized methods ("<a href="https://www.worldpop.org/methods/populations" target="_blank">bottom-up</a>" and/or "<a href="https://www.worldpop.org/methods/populations" target="_blank">top-down</a>") developed for the latest data available from each country. 
They can also be visualised and explored through the <a href="https://apps.worldpop.org/woprVision/" target="_blank">woprVision App</a>.
<br/>
The remaining datasets in the links below are produced using the "<a href="https://www.worldpop.org/methods/populations" target="_blank">top-down</a>" method, 
with either the unconstrained or constrained top-down disaggregation method used. 
Please make sure you read the <a href="https://www.worldpop.org/methods/top_down_constrained_vs_unconstrained" target="_blank">Top-down estimation modelling overview page</a> to decide on which datasets best meet your needs. 
Datasets are available to download in Geotiff and ASCII XYZ format at a <u>resolution of 3 and 30 arc-seconds (approximately 100m and 1km at the equator, respectively)</u>:

Older datasets produced for specific individual countries and continents, using a set of tailored geospatial inputs and differing "top-down" methods and time periods are still available for download here: <a href="https://www.worldpop.org/geodata/listing?id=16">Individual countries</a> and <a href="https://www.worldpop.org/geodata/listing?id=17">Whole Continent</a>.
  
Data for earlier dates is available directly from WorldPop.
