The Southern Europe consists of three peninsulas located in the extreme south of the European continent. Also called the Mediterranean Basin, it is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation.
Is Portugal the poorest?
Interesting article from diercke
Southern Europe – Economy
The Mediterranean has four very different heterogeneous economies: the relatively high cost EU countries, including prolonged crisis transition countries located in Southeast Europe and Cyprus, the Arab countries of West Asia and the developing countries of North Africa. Turkey mediates between the Islamic West Asia and Europe. Israel holds a special position.
The EU countries
Some of the economically strongest regions are Portugal, Spain, France, Italy and Greece . However, socio-economic disparities, economic and regional policy debates dominate these regions with a north-south divide especially more notable in Italy.
The commodity potential of southwestern Europe is low, although several industrial areas (such as Northern Spain) owe their origin to mineral resources. This is partly due to where a structural adjustment process is behind the steel industry. The steel plant in Taranto is a typical example of the Italian attempt to give impetus for development using major state industries in southern Italy.
The textile and clothing industry is of continuing importance, which emerged in respect of the value-added share of exports. Due to the high labour costs, Italy and France in particular are forced to remain competitive through high quality. Car production has an important growth and export industry mostly for Italy, France and Spain.
The aerospace industry as a unique high-tech industry has been based in France, Italy and Spain. The Airbus production and EU space programmes have gained a lot in importance, both in the military and private sectors. High-tech fields of electrical engineering and electronics are located primarily in metropolitan areas with their agglomeration advantages (Ile-de-France, Rhône-Alpes, Lombardy).
Because of structural problems, Greece and Portugal, like Spain and Italy, receive significant development assistance from the Regional Fund of the Union. The whole of the coastal area is an important tourist region.
No, Portugal is not the poorest and the most backward country in Southern Europe based on the information below that I found online.
The countries/territories of Southern Europe are:
a) Let’s look at mean wealth per adult (in US dollars)*:
*No data for Andorra, San Marino, Vatican City, and Gibraltar.
b) Now let’s look at GDP per capita (data from the IMF in US dollars):
c) Democracy (data from v-dem):
*No data for Andorra, San Marino, Vatican City, Malta and Gibraltar.
d) LGBTQ+ rights*:
*No data for Vatican City and Gibraltar.
In conclusion: Portugal is the 4th richest (6th in terms of GDP per capita) , 1st in democracy and 2nd in LGBTQ+ rights in Southern Europe, pretty far from the adjectives used to describe it in this question.
