Spatial inequalities within Latin American countries have historically attracted the interest of academics, policymakers, and international agencies. This paper aims to provide a multidimensional diagnosis of provincial development gaps in Argentina, in order to identify the location of policy priorities. Therefore, we built a large database, which covers seven development dimensions, and applied multivariate analysis techniques to overcome some analytical limitations of previous studies. Results show the stability of provincial development gaps between 2003 and 2013 and some heterogeneity within geographic regions. Instead, cluster analysis offers a better classification of Argentine provinces according to their development gaps, which can help the government to prioritize the places where development policies are strategic.
