Notes: Estimates of population centre greenness are based on the normalized difference vegetation index (NDVI) from MODIS. Water areas have been excluded. Includes population centres south of 60° latitude based on the 2016 population centre boundaries for all years to ensure consistency. Change in greenness compares the point in time to 2001 and does not represent a trend over time. For more information, see Appendix A.
