I need a list of the central points (centroid) for all countries:

China: lat/long (coordinates of the most central point in China)
France: lat/long (coordinates of the most central point in France)


Frank Donnelly provides a CSV file of country centroids that's based on data taken from the GeoNames Server, but hand curated by Frank. The data was last updated in February 2012.

May 2018

The former source isn't available anymore, here is a newer one, with lots of infos on the countries (incl. Centroids), and possibility to download the data in several formats. https://worldmap.harvard.edu/data/geonode:country_centroids_az8

There's also a similar question over at Stackoverflow: Need a list of all countries in the world, with a longitude and latitude coordinate, which includes a couple of approaches for generating such a list from other data sources.


You can retrieve this information using R like this:


# get world map
wmap <- getMap(resolution="high")

# get centroids
centroids <- gCentroid(wmap, byid=TRUE)

# get a data.frame with centroids
df <- as.data.frame(centroids)

#>                     x         y
#> Aruba       -69.97345  12.51678
#> Afghanistan  66.00845  33.83627
#> Angola       17.53646 -12.29118
#> Anguilla    -63.06082  18.22560
#> Albania      20.05399  41.14258
#> Aland        20.03715  60.20733

# plot



You can get country centroids using Python and GeoPandas.

import geopandas as gpd
import pandas as pd

# Access built-in Natural Earth data via GeoPandas
world = gpd.read_file(gpd.datasets.get_path('naturalearth_lowres'))

# Get a list (dataframe) of country centroids
centroids = world.centroid
centroid_list = pd.concat([world.name, centroids], axis=1)

# Plot the results
base = world.plot(column = 'name', cmap = 'Blues')
centroids.plot(ax = base, marker = 'o', color = 'red', markersize = 5)

In [1]: centroid_list
                           name                                              0
    0               Afghanistan  POINT (66.08669022192834 33.85639928169076)
    1                    Angola  POINT (17.47057255231345 -12.24586903613316)
    2                   Albania  POINT (20.03242643144321 41.14135330604877)
    3      United Arab Emirates  POINT (54.20671476159633 23.86863365334761)
    4                 Argentina  POINT (-65.17536077114174 -35.44682148949509)
    5                   Armenia  POINT (45.00029001101479 40.21660761230144)
    6                Antarctica  POINT (20.57100056984261 -80.49198288284349)
    ... and so on ...

Most of the links mentioned above are dead. However I found this csv file containing Geographic centers of countries in lat-long coordinates.
