The economy emerged from recession in 1997 and has shown strong aggregate growth since then. The estimated GDP for 2017 is US$61.5 billion, up significantly from the US$52.6 billion in 2015 while the estimated 2017 per capita (purchasing power parity) is US$12,382. Inflation remained around 4% to 5% per annum for several years up to 2015 but then dropped to 0.7% in 2016; it was expected to rise to a still moderate 2.8% by the end of 2017 In 2017, Costa Rica has one of the highest standards of living in Central America in spite of the high poverty level, which dropped by 1.2% in 2017 to 20.5% thanks to reducing inflation and benefits offered by the government. The estimated unemployment level in 2017 is 8.1%, roughly the same as in 2016. The country has evolved from an economy that once depended solely on agriculture, to one that is more diverse, based on tourism, electronics and medical components exports, medical manufacturing and IT services. Corporate services for foreign companies employ some 3% of the workforce. Of the GDP, 5.5% is generated by agriculture, 18.6% by industry and 75.9% by services (2016). Agriculture employs 12.9% of the labor force, industry 18.57%, services 69.02% (2016) Many foreign companies operate in the various Free-trade zones. In 2015, exports totalled US$12.6 billion while imports totalled US$15 billion for a trade deficit of US$2.39 billion. The growing debt and budget deficit are the country's primary concerns. By August 2017, Costa Rica was having difficulty paying its obligations and the President promised dramatic changes to handle the "liquidity crisis". Other challenges facing Costa in its attempts to increase the economy by foreign investment include a poor infrastructure and a need to improve public sector efficiency.
