MPRA Paper from University Library of Munich, Germany

Abstract: We study the decennial log-growth population rate distributions of France (1990-2009), Germany (1996-2006), Italy (1951-1961, 2001-2011) and Spain (1950-1960, 2001-2010). It is obtained an excellent parametric description of these log-growth rates by means of a modification of the normal distribution in that the tails are mixed by means of convex linear combinations with exponential distributions, giving rise to the so called “double mixture exponential normal”. The normal distribution is not the one empirically observed for the same datasets.
