That was Germany's GDP growth in 2014, the highest rate since 2011, when it was 3.6%. In 2012, Germany's GDP grew by 0.4% then by a more timid 0.1% in 2013. Over the past ten years, average growth is 1.2%. Breaking the 2014 figure down, exports expanded by 3.7%, private spending by 1.1% and public expenditure by 1%.
