US State Plane Coordinate System Map.

The State Plane Coordinate System (SPS or SPCS) is a set of 124 geographic zones or coordinate systems designed for specific regions of the United States. Each state contains one or more state plane zones, the boundaries of which usually follow county lines. There are 110 zones in the continental US, with 10 more in Alaska, 5 in Hawaii, and one for Puerto Rico and US Virgin Islands. The system is widely used for geographic data by state and local governments. Its popularity is due to at least two factors. First, it uses a simple Cartesian coordinate system to specify locations rather than a more complex spherical coordinate system (the geographic coordinate system of latitude and longitude). By using the Cartesian coordinate system’s simple XY coordinates, “plane surveying” methods can be used, speeding up and simplifying calculations. Second, the system is highly accurate within each zone (error less than 1:10,000). Outside a specific state plane zone accuracy rapidly declines, thus the system is not useful for regional or national mapping.

eCollegeFinder is back with another map series, this time looking at which colleges charge the most for on-campus room and board in each state. We all know how expensive college is these days. From massive tuition fees to costly text books, it really burns a hole in the pocket. Aside from tuition, room and board is usually one of the top expenses for each student. This got us thinking, which colleges charge the most for on-campus living?

Decorative map of North and South America published in 1631 by Willem Blaeu

Willem Janszoon Blaeu. “Americae nova Tabula. Auct: Guilielmo Blaeuw.” Amsterdam: W.J. Blaeu, 1631. Third state. 16 x 21 5/8. Engraving. Lovely, original hand color. Narrow margin at left, as issued, just touching neatline at bottom; some new margin added for matting. Very good condition. Latin text on verso. Burden 189.

One of the most sought-after and decorative maps of North and South America, a gem by Willem (Guilielmus) Janszoon Blaeu. Willem Blaeu (1571-1638) was the progenitor of the famous Blaeu cartographic firm of Amsterdam. He studied astronomy and sciences with Tycho Brahe, and in 1599 established a globe and instrument making business which soon expanded to include cartographic and geographic publishing. This firm was to go on to become the largest and most important cartographic publishing firms in the world, run by his sons Cornelis (until his death in 1642) and Joan. The maps issued by the Blaeu firm are known for their fine engraving, coloring and design, and have been called “the highest expression of Dutch cartographical art.”

This lovely map of North and South America is typical of the work of Willem Blaeu, with an up-to-date topographical depiction surrounded by decorative borders. The geographical image is fascinating, with accuracies and inaccuracies combined in a mix that reflects the best available knowledge of the day. The general picture is very good, but many cartographic myths are represented including the fictional islands of Frisland and Brasil and the famous non-existent city of gold, El Dorado. Decoratively, the map is one of the most beautiful of the golden age of Dutch cartography. Along the top are nine vignette views of the major cities on the continent, while ten pairs of figures line the sides illustrating the dress of the local inhabitants. The decorative features continue within the map area, with numerous sailing ships and sea monsters plying the waves, as well as vignettes of natives in South America. With its intricate flourishes, fascinating ethnological and historic detail, lovely original color, this is a superb item of seventeenth century art and cartographic history.

Percentage of population in each country that is classified as being White or of European ancestry

holytriplem:

Here is a map showing the percentage of people in each country/state/province that are officially identified as being purely White or of purely European descent (ie no mixed-race people), created in response to the one posted by /u/worldbeyondyourown about a week ago, but corrected for issues such as, you know, assuming Muslims couldn’t be White. Having said that, however, it is still very hard to define who is ‘White/European’ and who isn’t, for two main reasons:

-In the case of Latin American countries, it is hard to draw the line between White and Mestizo/Mulatto, and so the status of eg. Castizos is quite hard to determine. You therefore have VERY wildly varying statistics when it comes to the concentration of White people in each country in Latin America. I have therefore taken all the stats about Latin America from the table on the left. And if you compare it to the Latinobarometro table to the right, you can see how different some of the percentages are. In particular, I have decided to leave Argentina blank, as the 97% stated by the CIA World Factbook is clearly a gross overestimate.

-In the case of indigenous peoples in the Caucasus and Siberia, it is hard to determine which ethnic group can be classified as being ‘European’ and which cannot. I have therefore very arbitrarily decided on an ethnolinguistic division: Caucasian peoples and Finno-Ugric peoples (with the exception of the Khanty and the Mansi) would be classified as White, while Altaic and Samoyedic peoples would be classified as non-White.

For this map, I have taken all my statistics from the CIA World Factbook where possible, or various Wikipedia pages (usually the ones titled ‘Demographics of ) where not. For most African and Asian nations, if I found no data about the concentration of White people I simply labelled them as being pink, with the exception of some nations eg. Singapore or the UAE, where I have good reason to believe that the resident White population is non-negligible. Most of Australia has been left blank, as the Australian census classifies people according to ancestry as opposed to race, which means it takes quite some effort to determine which of the 150 odd ancestries listed are White and which aren’t.

Feel free to contribute any better data if you can find it.
