In 2005 the growth rate declined sharply and fluctuated steadily until 2012. The GDP is based on the spending patterns from 1990.
GDP per capita growth rate
The GDP per capita growth rate moved similar to the GDP the difference is in the figures.
Inflation rate
From 1990 the inflation rate increased by more each year up to 1994 when it decreased slightly and rose sharply thereafter (1995). It then decreased in 1996 and began to fluctuate in the years that follow until 2012.
