Understanding Key Demographic and Urban Development Concepts

Life Expectancy

Life expectancy is an indicator expressing the average number of years a person can expect to live after a certain age, based on mortality conditions. “Life expectancy at birth” is used for comparisons, revealing mortality differences between regions. It represents the average lifespan an infant can expect, given the mortality intensity of the reference population.

Real Growth

Real population growth adds natural increase to net migration. Since 2001, Spanish population growth accelerated

Industrial Processes and Energy Sources

Agribusiness

Industrial processing of agricultural raw materials to produce consumer goods for food, feed, or other industrial processes (e.g., flour mills, canning, sugar).

Economies of Scale

Large-scale, low-cost production.

External Economies

Benefits obtained by companies from external factors, such as proximity to ancillary and complementary businesses, infrastructure, and common facilities, which reduce costs and increase profits.

Final Energy

Usable energy forms derived from the transformation of

Greenhouse Effect and Global Warming

The greenhouse effect is a natural phenomenon where the atmosphere absorbs some of the Earth’s energy, preventing it from escaping back into space. Human activities, primarily the release of greenhouse gases like CO2, intensify this effect, leading to global warming.

Consequences of Global Warming

  • Melting polar ice caps and rising sea levels
  • Loss of biodiversity due to temperature changes that many animals cannot adapt to.

The Enlightenment and its Impact on the Spanish Ancien Régime

The Spanish Ancien Régime

The Ancien Régime in Spain, a product of feudalism’s decline, persisted until the Portuguese Liberal Revolution of 1789, coinciding with the French Revolution. Politically, under Hapsburg and Bourbon rule, the system fluctuated between authoritarianism and absolute monarchy. Governed from Madrid, the political-administrative structure, influenced by the Nueva Planta decrees, lacked a unified Spanish state. Different kingdoms coexisted under the king’s rule.

Rural Areas in Spain: Influencing Factors and Evolution

Rural Areas in Spain

Influencing Factors

Physical Factors

Physical factors, though less impactful than in the past due to technological advancements, still play a role in shaping rural areas. These include:

  • Relief: Abundant high altitudes and steep slopes hinder mechanization and contribute to erosion.
  • Climate: Low and unpredictable rainfall (thunderstorms, hail), extreme temperatures (intense heat and cold), and varying degrees of aridity characterize much of the area.
  • Soils: Predominantly poor quality

Demographic Transition in Spain: A Comprehensive Analysis

Demographic Terms

Vegetative Growth

Balance between births and deaths in a year.

Total Growth

Considers both vegetative growth and net migration.

Net Migration

The difference between immigrants and emigrants.

Total Fertility Rate

Number of children per 1,000 women aged 15 to 49 years.

Mortality Rate

Number of deaths per 1,000 inhabitants in a specific period or year; it is expressed as x per thousand.

Infant Mortality

Number of deaths before one year of life per 1,000 live births.
