Population

Data and experiments with world population densities for comparison to addresses. More information at this post: http://mike.teczno.com/notes/openaddr/population-comparison.html

Includes gridded population data from two datasets, Gridded Population of the World (GPW), v4 (2015, UN-adjusted) in data/gpwv4-2015.csv.gz and Geographically Based Economic Data 4.0 (2005) in data/gecon.csv.gz.

GPWv4 Estimate

Contents of data/gpwv4-2015.csv.gz derived from gpw-v4-population-count-adjusted-to-2015-unwpp-country-totals_2015.tif raster dataset, available at http://beta.sedac.ciesin.columbia.edu/data/set/gpw-v4-population-count-adjusted-to-2015-unwpp-country-totals/data-download

Columns:

• iso_a2, iso_a3: ISO 2-letter and 3-letter country code.
• lat, lon: southwest corner of grid square.
• size: size of grid square, 1.0 or 0.1.
• year: GPWv4 population estimate year.
• population: Number of people in this grid square.

Sample rows:

iso_a2	iso_a3	lat	lon	size	year	population
FJ	FJI	-180.0	-20.0	1.0	2015	1.407
US	USA	-180.0	51.0	1.0	2015	0.0

1,583,241 total rows: 21,018 at size 1.0 and 1,562,223 at size 0.1.

data/gpwv4-2015-merc.csv.gz is a variation on data/gpwv4-2015.csv.gz, with population calculated for web mercator map tiles instead of lat/lon squares.

Columns:

• iso_a2, iso_a3: ISO 2-letter and 3-letter country code.
• z, x, y: coordinate location.
• year: GPWv4 population estimate year.
• population: Number of people in this grid square.

Sample rows:

iso_a2	iso_a3	z	x	y	year	population
FJ	FJI	8	0	139	2015	2250.198
US	USA	8	16	54	2015	4713.011
