The Maps Of The Week


This calendar week I was actually impressed alongside how Chicago's Million Dollar Blocks used a choropleth map of Chicago to tell the story behind the huge terms of incarcerating citizens. Illinois volition pass 1.4 billion dollars on the Department of Corrections. H5N1 large proportion of that coin volition endure spent on locking up Chicagoans from the low-income neighborhoods on the westward as well as southward sides of the city.

Chicago's Million Dollar Blocks maps how much coin is beingness spent on incarcerating individuals from each Chicago block. H5N1 large let out of these blocks inward the westward as well as southward sides of the urban inwardness are costing the urban inwardness over a i chiliad one thousand dollars. The information is based on judgement lengths as well as on an estimation that the Department of Corrections spends around $22,000 per twelvemonth for each inmate.

The map includes 2 principal layers: All Offences & Drug-Related. If y'all mouse-over a block on the map y'all tin laissez passer the axe persuasion the terms to the state of both drug-related incarcerations as well as for all offences. If y'all zoom out on the map y'all tin laissez passer the axe besides persuasion a choropleth layer showing the terms of incarceration at the neighborhood level.


This calendar week the Oregonian besides used a choropleth map to visualize the buildings inward the urban inwardness most probable to endure earthquake damage, based on edifice age. 

In 1974 Oregon enacted its start statewide edifice code. In 1993 western Oregon adopted its start seismic standards. Franz Rad, a professor of civil & environmental technology scientific discipline at Portland State University, argues that these dates render a "broad-brush await at the vulnerability of buildings".

Portland buildings that predate 1974 are probable to endure the most vulnerable to seismic activity. Buildings erected afterward 1974 are ameliorate built, as well as those built afterward 1993 are fifty-fifty better.

Earthquakes: How Vulnerable are Portland’s Buildings? takes the Portland edifice historic menstruum information as well as colors the urban inwardness edifice footprints to exhibit buildings constructed earlier 1974, those constructed betwixt 1974 & 1993 as well as buildings erected afterward 1993. You tin laissez passer the axe thence role the map to assess the probable vulnerability of whatsoever Portland edifice during an earthquake.


El Pais has besides created an informative interactive map, to tell the story of Castilian municipality debt.

The Variation of Municipal Debt inward the Last Legislature map shows which Castilian municipalities stimulate got increased or lowered their degree of debt since 2011. Municipalities colored cherry on the map stimulate got increased their levels of debt as well as the municipalities inward dark-green stimulate got reduced their degree of debt. You tin laissez passer the axe detect out the exact degree of an private municipality's debt past times clicking on it on the map.

It is difficult to instruct a consummate overview of the numbers of municipalities that stimulate got managed to cut their debt as well as those that stimulate got increased their overall debt simply from the map view. It looks to me that almost one-half of the municipalities are performing ameliorate economically as well as almost one-half are performing worse. The proficient intelligence is that many of the larger cities, such equally Madrid, Barcelona as well as Valencia all seem to stimulate got managed to cut their debt since 2011.
