Cities where the rich get rich and those where the poor get poorer

THE ECO / INTERACTIVE CONTENT SCAN – According to a study by the Observatory of Inequalities, the income threshold of the richest 10% has increased by 4,500 euros in three years in Boulogne-Billancourt, when that of the poorest has fallen by 1000 euros at Le Mans.

We know, but where do we get rich or impoverish the most? In his, published this Thursday, looks at these cities where the wealthy categories “are not necessarily the richest in France, but where the dynamic [d’enrichissement] is the strongest ”.

Based on data from INSEE, the Observatory compared the annual income of inhabitants of the 150 largest cities in France (the equivalent of a threshold of around 40,000 inhabitants) between 2008 and 2011. In percentage, c t is in Annecy, Nanterre, Ajaccio and Lille that the income of the richest has increased the most. In Île-de-France, Fontenay-sous-Bois, Colombes, Alfortville and even Meudon, the income of the richest 10% has risen 7 to 8% in three years. If we no longer think of a percentage but in euros, the standard of living of the better-off – which has increased from 2,000 to 3,000 euros in many municipalities – has increased the most in Neuilly-sur-Seine (+7,200 euros), Boulogne-Billancourt (+4500 euros), Annecy and Suresnes (+4100 euros). Neuilly-sur-Seine remains the city where the disposable income of the top 10% is the highest (111,700 euros per year for a single person).

The Observatory of inequalities underlines a reversal in 2008: until then, “inequalities increased from above with the surge of high incomes”. But since then, “largely because of rising unemployment […], they are also stretching from the bottom with a drop in low incomes ”. This decrease first affected Roubaix, where the annual income threshold of the poorest 10% fell by 99%, from 287 euros in 2008 to… 2 euros in 2011. This is an “income”. tax declared for the equivalent of one person. It does not include taxes or social benefits, [ni l’inflation]: our data therefore tend to exaggerate inequalities, ”recognizes the Observatory. Béziers (-45% to 803 euros), Charleville-Mézières (-37% to 1,637 euros) and Perpignan (-33% to 669 euros) follow. For three municipalities, this threshold loses more than 1000 euros in just three years: Limoges (-1128 euros), Le Mans (-1070 euros), and Tarbes (-1072 euros).

Overseas cities, first in terms of inequalities

In the vast majority of cases, explains the Observatory, the incomes of the richest have increased by 4 to 8% and those of the poorest have suffered an equivalent drop. Even when it increases, the income of the poorest grows, in euros, less quickly than that of the richest. “Logical, since the increases [salariales] are generally calculated as a percentage ”. But there are exceptions: in 12 municipalities out of the 150 taken into account, including Courbevoie, Puteaux, Aubagne or Cagnes-sur-Mer, income increased faster, in percentage, for the poorest 10% than the The richest 10%.

If the sample had been expanded to more than 150 cities, the result would have been different, admits the Observatory, which did not take into account small municipalities because “inequalities [y] are generally less ”. The ranking would have been particularly upset if the cities of the overseas departments had been included. “They would occupy all of the first places in terms of inequalities and low income: the poorest of the overseas departments have very low incomes, while the richest have incomes comparable to the populations of wealthy metropolitan cities”.
