Este documento de trabajo presenta una tipología del suelo rural/urbano a partir del manejo de bases de datos de coberturas del suelo, en lugar del uso de información demográfica, que suele ser el procedimiento más habitual. El punto de partida es la idea de que los procesos de urbanización...

This working paper examines differences in life expectancy at birth across time, space and sexes, focusing on two origins: 1) changes in age-specific mortality rates; and 2) changes in age-specific mortality rates by cause of death. We use decomposition methods in life expectancy differentials...

This working paper proposes an indicator that integrates life expectancy with the demographic structure of the pop ulation for a given society, combining the simple indica tors of mortality and aging. Life expectancy at birth is in-dependent of the demographic structure of the population and is,...

Este documento de trabajo examina la posibilidad de construir una grid de población a partir de información pública, el nomenclátor en lo que respecta a la población y la cartografía en lo que hace referencia a información auxiliar sobre usos del suelo. El método propuesto es un método...

This working paper presents a simple and locally optimal test statistic for the Pareto law. The test is based on the Lagrange multiplier (LM) principle and can be computed easily once the maximum likelihood estimator of the scale parameter of the Pareto density has been obtained. A Monte Carlo...

This working paper quantifies, at a regional level (NUTS3), terrain ruggedness, and compares it with the average altitude of the region. Altitude is an often-used variable introduced in gravitational models of population or activity location as a measure of physical geography, to pick up a...

Este trabajo contribuye a la literatura empírica sobre la distribución del tamaño de las ciudades, articulada en torno a la ley de Zipf, utilizando la evidencia proporcionada por los municipios españoles a lo largo del siglo XX. Comienza con una serie de objeciones a la base de datos de...

In the literature there are a number of generalizations of the Gini coefficient which inherit most of its appealing properties. These families allow the incorporation of different value judgments and all of them are more sensitive to transfers among the poorest individuals in society than to...

This working paper looks at a geographical feature that, to our knowledge, has not been investigated in Spain so far, terrain ruggedness. Using geographical information systems and two public access digital elevation models we construct a terrain ruggedness index that quantifies topographic...

This working paper translates the global database of the Climate Research Unit from the University of East Anglia (<http://www.cru.uea.ac.uk/>), known as CRU TS 2.1, into regional data for Spain. This transform is carried out at the level of both autonomous regions (comunidades autónomas, NUTS 2) and provinces (NUTS 3)....
