The method of Principal Component Analysis on regional data allowed us to note a problem of favoritism of the State for the Greater-Tunis areas and the Central-East areas. Then, a Gini index for each variable is calculated to measure the extent of infrastructure inequalities. Using convergence tests, it is shown that the unequal endowments in infrastructure are relatively low and falling. Key words: Regional Inequality, Investment in Infrastructure, Convergence JEL Classification-D63, H54, O18 INTRODUCTION: Sustained economic growth permits the creation of decent jobs and the improvement of the standard of living of all citizens. However, economic growth in Tunisia has not benefited all regions equitably, in spite of efforts made over the last decades.
