Economic problems and of political class in the surveys of CIS, 1985-2009 (curious graphs LXXXVI)

Since they know, CIS has done publics today the results of the barometer corresponding to October, 2009. On having checked them and having updated the series that I continue, I have realized that they have begun to publish a table with the information of the question by three principal problems of Spain and that it goes back 1985. Those that Wonkapistas continues know that I have prepared long series on some of these problems, like the immigration or the housing, or, very recently, on the problems relative to the political class. Now, CIS gives us the made work, and it is already not necessary to go consulting the results of the barometers one for one to complete the series that we are interested in. Very kind.
Making use of this new tool, next I offer them a few graphs that can be interesting to place in perspective diacrónica some of the most excellent problems in the current moment of economic crisis and political crisis.
First, a graph with the principal economic problems.

Since they see, the mention of the unemployment as one of three principal problems of Spain was maximum partly of the eighties and probably at the beginning of the nineties. It fell down clearly from 1997 till the end of the year 2000, it was supported later and fell down again enough from the beginning of 2004. With the new crisis, the mentions of the unemployment have grown with rapidity, up to being located in new maximum, low, anyhow, to those of the eighties.
The truth is that the mention of the unemployment continues very closely (big finding!) the evolution of the valuation of unemployment, since they can verify in the following graph.
In the last long decade, the mention of the unemployment has moved inversely that of the problems of housing, which were climbing to "top 3" of the Spanish problems as the unemployment valuation was falling down and the prices of the housing were growing. And something similar happens with the " problems "of the employment", that, I believe, usually groups questions as those of an excessive presence of temporary contracts.
The mentions of problems that remain labeled as "of economic nature" also continue closely the evolution of the business cycles. Anyhow, it is interesting to see how these mentions are falling down in the last months, although the unemployment does not diminish and the crisis I had not just abated.
Probably, it is explained because other problems, not economic, are climbing to "top 3". Perhaps those that they affect to the political class, as it happened in 1994/1995 and it happens now.

I have supported the scale 0 to 100 of the axis of arranged so that they could appreciate of a glance that the mentions of problems of the political class, as CIS has codified and unified them in three series, turn pale before the mentions of economic problems. In spite of everything, the evolution is observed relatively well: maximum levels in the 1993/1995 political crisis, especially in what concerns the corruption, relatively low levels later, up to the rise of last months, and the quite clear increase in the last barometer of the mentions to the corruption, which have happened from the 1,4 to 5,1 %. Given the panorama of scandals of corruption that they affect to the principal parties, it would be no wonder that this number kept on climbing in the next months. Anyway, that those of CIS have behaved. Now only it is missing that they give us tracks of how they do the kitchen of estimation of vote ;-)
