1. I download GRUMP 2000 population count data set. It sees that maximum population count is 1,346,772 in the cell of that data set. I would like to know that is right or not, because I think that the value is very large. Could you give me advice about maximum population count in GRUMP?

  2. How was the Data Context layer created?

  3. How do I use the Data Cart?

  4. How should I cite the GPWv4 data?

  5. How should I cite the GPW3 data?

  6. What source data is used in GPWv4?

  7. What year(s) is this data from?

  8. What are the restrictions on use and redissemination of data?

  9. I see you have country-level estimates for the low elevation coastal zone data. Is it possible to get the gridded data?

  10. What are the restrictions on use and redissemination of data?

  11. How is a global raster created from tabular census data and boundaries?

  12. I was excited to see you have anthropogenic biome data, which would be useful in my research. What are the differences between the Anthropogenic Biomes of the World, v1 data and the Anthropogenic Biomes of the World, v2 data for 2000?

  13. What is the projection used for the data?

  14. Why can't I make the Import71 work with the GPW data?

  15. In the Urban extents data, how were the urban areas identified?

  16. What years are the data available for?

  17. What is the difference between the Population Count and the UNWPP-Adjusted Population Count data sets? And between the Population Density and the UNWPP-Adjusted Population Density data sets?

  18. How up to date are the data in ENTRI?

  19. GPWv4 releases data for five years: 2000, 2005, 2010, 2015, 2020. Is it advisable to compare data sets of different years in order to assess changes in population density over time? Are there constraints in using the GPWv4 target year data sets as a time series?

  20. What does a zero in the population density grid mean? What does No Data mean?
