Spain has almost 50 million inhabitants in 2013, more than in the past, due to a higher birth rate than death rate and immigration. Most people live along the coast or in Madrid, with the center of Spain being less populated. The economy relies on services (69% of active population), industry (26%), and agriculture (5%). Spain is a constitutional monarchy divided into 17 autonomous communities and 2 cities, with the monarch as head of state and parliament approving laws.
