Internet Censorship vs Freedom of Expression

Zachary Sniderman on Mashable published an interesting article titled, Just How Open Is Your Internet?. I thought the featured map looked a little bit fishy – Mongolia has less internet censorship than Sweden? Really? What does that mean? It seemed to me that there might be something missing from the account. To his credit Mr Sniderman does note

…it raises some inherent problems with defining “censorship.” For example, screening out child pornography and illegal file sharing technically registers as “censorship” even though most people wouldn’t consider that a human rights offense.

Even accounting for his concerns it still looked a bit odd to me.

Economics and the Internet’s Large-Scale Topology

Distribution of the Internet around the world. (Top) Worldwide router density map obtained using NetGeo tool to identify the geographical location of 228,265 routers mapped out by the extensive router level mapping effort of Govindan and Tangmunarunkit. (Bottom) Population density map based on the CIESIN’s population data. Both maps are shown using a box resolution of 1 degree by 1 degree. The bar next to each map gives the range of values encoded by the color code, indicating that the highest population density within this resolution is of the order 10**7 people/box, while the highest router density is of the order of 10**4 routers/box. Note that while in economically developed nations there are visibly strong correlations between population and router density, in the rest of the world Internet access is sparse, limited to urban areas characterized by population density peaks.

This graph and the explanation above are taken from Modeling the Internet’s Large-Scale Topology by Soon-Hyung Yook, Hawoong Jeong, Albert-Laszlo Barabasi. Department of Physics, University of Notre Dame, Notre Dame, IN 46556, USA.
