According to "Insee first" No. 1229 of March 2009, "the value of the national wealth has multiplied by eight between 1978 and 2007: it has doubled in words real, while asset prices have more than quadrupled, worn especially by the strong progress of those real estate over the past ten years."
Housing, and the land on which they are or will be built, are more in the hands of the relatively elderly and young. Thus, in the investigation Heritage 2003-2004, Insee is the rate of detention of a principal residence, according to the age of the "reference person" of the household:

13.7 if it has less than 30 years;
46.1 if it was between 30 and 39 years;
60.9 if it was between 40 and 49 years;
67.5 if it was between 50 and 59 years;
69.5 if it was between 60-69 years;
61.4 if it was 70 years or more.
This means that net purchases of land built or build (direct, or by sponsor intervening in the case of apartments) occur mainly between 30 and 50 years. Who are the vendors NET, recipients of the escalation of prices Households have, where appropriate following a legacy (the average age of inheritance has risen at the same time as the average age of death), and found that they can dispose of it in whole or in part, that is mostly of retired people or who are close.
But the price of the built land or building exploded. The price of the "underlying lands" those who support a dwelling or are purchased for this purpose has been multiplied by twenty between 1978 and 2007, indicates the Insee, while the multiplier is 4 for the whole of the heritage. In 2007 the underlying land accounted for 35 of the heritage of households, compared to 27 for housing stricto sensu.
This implies a considerable transfer of young households towards older, and retirees especially. Returning to the labour market are today view to give them a large proportion of the wealth they create their work: contributor to retirement funds and health insurance (funded 90 by assets, it affects more than 40 of its expenditures to retirees); as rents; (possibly implicit) purchasing of built land or building; and by paying interest on their giant real estate loans (part of the interest that banks pay holders of financial investments).
For young households, whose much, were appropriate, do not enter professional life with extreme ease, the situation became untenable. In "Les Echos" of November 5, 2008, Jacques Friggit believes that the purchase of a principal residence came to absorb on average five years of income for the couple, three in the year 2000. Of course, falling real estate prices in progress will improve the situation, but will it suffice with regard to land if one does not cure some causes of their high prices
The France has a population density two to three times lower than that of many other European countries: Germany, Belgium, Netherlands, United Kingdom, etc. Why then if high prices for the built land or to build The insufficiency of the tender wishes to factors other than the physical scarcity of the land. It would be useful to determine which (land use plans transport policy etc.) as well as their respective importance, and to examine what means would change the situation. Not doing so would be to accept that our country is the place of an abuse of the assets by the inactive.
