Following the revocation of George Town's free port status in the 1960s, the state suffered economic decline and massive unemployment. The state government at the time led a push to reorient the economy towards hi-tech manufacturing, successfully recovering Penang's economy and lending the state its moniker the Silicon Valley of the East. Growing recognition of George Town as a bustling tourist destination, particularly since the city's inscription as a UNESCO World Heritage Site in 2008, also boosted the state's services sector, and today, both the manufacturing and services sectors are the two strongest economic pillars of Penang. Moreover, the state enjoys one of the lowest unemployment rates and Gini coefficients within Malaysia, as well as the second highest gross domestic product (GDP) per capita within the country after Kuala Lumpur.
