It can be seen how the production stays in continuously increase since 1996 and then remains constant between 2004 and 2012. The peak ocurres at the year 2013 and the copper production stays strong at the present. The information has been acquired from the Chilean Copper Commission.

Relevant mining projects in the municipalities with the highest mining workers / population proportion (50%+)

The reason measure poverty using Small Area Estimation (SAE) in this graph is to have numbers close to reality at municipal scale, this because big estimations fails in establishing good values in small areas like a commune, so for good characterization this methodology is needed. The highest poverty value in the year 2013 is located in the municipality of Tierra Amarilla with a value over 11 percent.

Municipal Poverty vs CMF

Correlation coefficient between poverty and Common Municipal Fund (CMF)

The value below shows a medium intensity and directly proportional relation between the dependency ratio in the Common Municipal Fund (CMF) of the municipalities of Chile and the percentaje of people in conditions of poverty in the same municipalities.

Municipal budget 2015 (Barplot)

The following graph show the municipal budget in the selected municipalities. Antofagasta haves the highest value in mining patents followed by Sierra Gorda and Calama. As the graph shows the value of the CMF and the road taxes are very relevant in the municipal budget.

Public investment per capita

First, the database was filtered by tipology “PROYECTO” and the total value of projects in “Millones de pesos” (the value in USD only groups 38 projects and none of them in the municipalities of the study). Second, the duplicated values were removed of the database. Third, the total cost was grouped using the median by municipality and year of submission. Finally, the year values above 2002 were selected and the calculation of ratio was done merging the database with the population of the respective year.

The peaks of Sierra Gorda in 2004 are explained by construction of a theater, an school and a deportive complex, then in 2006 the investment was done mainly in highways, and finally in 2009 the construction of a semi-olimpic pool and another highways explain the high values.
