This makes it the sixth largest metropolitan area in the United States, the second-largest Urban agglomeration (behind Sao Paulo in Brazil) and the largest Spanish-speaking City (city proper). Greater Mexico City's GDP was $411 billion in 2011. This makes it one the most productive urban areas worldwide.  Mexico's GDP was generated by the city, which accounted for 15.8%. The country's GDP was 22% in the metropolitan area.  Mexico City, if it were an independent nation in 2013, would be the fifth largest economy in Latin America.
