This project has three main objectives:  - To map the public policies of the Portuguese diaspora and other countries with a significant diaspora;  - To typify the different public policies of the diaspora, i.e. their directionality (financial, ethnic, cultural, civic, political) and to define the concept and object that each country uses for its diaspora.  - To characterise and identify the main models of diaspora public policies in the different countries under analysis, identifying good practices in the different countries under study, and to make a comparison between the policies of the Portuguese state directed towards the Portuguese communities and those of the selected countries.
