Guest Map: Ratio of Mobile to Fixed Line Phones

Nice map and discussion by Slate/New America Foundation on the relationship between fixed and mobile telephony. The darker the color the more mobile phones relative to fixed lines in a country. Africa, the Arabian peninsula and South/Central Asia really stand out.

It is worth a trip to the original map as it contains lots of good juicy data.

Guest Map: Surnames in the U.S.

Just a cool map from National Geographic on the distribution of surnames (a.k.a. last names) in the United States. It is interactive so zoom on in and see what last name predominates in your neck of the woods.
