Human rights organizations such as Human Rights Watch and Amnesty International have increasingly criticized Venezuela's human rights record, with the former organization noting in 2017 that the Chavez and subsequently the Maduro government have increasingly concentrated power in the executive branch, eroded constitutional human rights protections and allowed the government to persecute and repress its critics and opposition. Other persistent concerns as noted by the report included poor prison conditions, the continuous harassment of independent media and human rights defenders by the government. In 2006, the Economist Intelligence Unit rated Venezuela a "hybrid regime" and the third least democratic regime in Latin America on the Democracy Index. The Democracy index downgraded Venezuela to an authoritarian regime in 2017, citing continued increasingly dictatorial behaviors by the Maduro government.
