In 2015, growth of the French economy strengthened: gross domestic product in constant euros increased by 1.3%, after + 0.6% in 2014. Household consumption accelerated and investment expenditure rebounded. Imports continued to rise at a faster rate than exports, so that the foreign trade contribution was negative. The purchasing power of household gross disposable income improved, mainly due to the dynamism of earned income and social benefits in cash. Purchasing power per unit of consumption grew significantly for the first time since 2010. The household savings ratio remained stable while the margin rate of non-financial corporations recovered significantly.
