The 2015 Systematic Country Diagnostic (SCD) concluded that El Salvador was "trapped" in vicious cycles of low poverty reduction and growth and argued for a "big push" in six priority areas. Three mutually reinforcing cycles hampered growth and shared prosperity: (i) low growth and violence, (ii) low growth and migration, and (iii) low growth, savings, and investments. The SCD concluded that a big reform push in six priority areas was needed to break these cycles. Despite progress in some of these areas, previous governments have not built consensus for the "big push" of simultaneous reforms to break the cycles. This SCD Update (the Update) builds on the SCD as follows: (i) updating the country context and assessing progress in poverty and growth, (ii) broadening the analysis to include a vulnerability lens, and (iii) rerunning the prioritization framework to confirm or update priorities.
