Macro Economy: Solid growth, but...

1. Inflation is not a problem

Sorce: trade economics
On the charts on the left, you can see the GDP of Tunisia has kept growing after the inauguration of Ben Ali. We have to recognize that his rule was successful to this extent. Not only GDP, but also GDP per capita is growing too.
You will be surprised that GDP per capita is still growing even after the PPP adjustment. Since 2010, food prices have been soaring (see World Bank), affecting the cost of living. 
In a long term trend, Tunisia is getting out its dependence on food imports. The basic economic results obtained under Ben Ali are thus far from dramatic, and have been praised by Foreign leaders as well as International Institutions (the IMF in 2010).

2. Regional Disparity is Serious

The chart on the left shows the long term agricultural transition in the Tunisisan economy. The green Line shows the agriculture's share in the Tunisian economy has been constantly decreasing.
As you can see in the chart below, the Tunisian economy is now more and more dependent on service sector and it concentrates on urban areas.
As I said before, disparity between rural and urban areas is large and also expanding. It stemmed  from  colonization and is still not resolved.

The World Bank pointed out in 1995 that almost two thirds of the population living under the poverty line lived in rural areas, though Tunisia is a highly urbanized society and more than 60% of the population live in urban areas. In this study, overall poverty rate in Tunisia is estimated to be 11.2% (see page 11) and in rural area, 19.1% of the population is suffering from poverty (4.6% in cities). The unemployment rate was 16.1% in 1989, higher than today (13%).
From the video below, you can see the marginalized and deprived situation of Tunisian rural areas. It seems that nothing changed after the 1995 World Bank  report.
