Essential Glossary of Demographic Terms

Aging of the Population

A demographic trend characterized by an increase in the proportion of the population aged 65 or over, often defined when this group exceeds 12% of the total population.

Active Population (Labor Force)

A group of people aged 16 or over who provide labor for productive activities, are available for work, and are seeking incorporation into the labor market.

Actual Population

The group of individuals physically present in a territory at a specific time, composed of usual residents and temporary visitors.

Baby Boom

A period of strong growth in birth rates, usually occurring after a period of crisis (e.g., war or economic depression).

Census

The Scramble for Africa: 1914 and Beyond

By 1914, Africa had transformed from a continent of isolated European strategic enclaves into a territory partitioned among major European powers:

• France: Possessed territories in Western Africa.
• Britain: Controlled lands from Egypt and Sudan down to South Africa.
• Other Nations: Germany, Spain, Italy, Portugal, and Belgium also held significant African territories.

The conquest of Africa sparked intense conflicts of interest. To prevent military escalation, the Berlin Conference of 1884 was held, though tensions between France and Britain persisted.

Consequences of Colonialism

The impact on the continent was profound:

• Destruction of indigenous traditions and lifestyles.
• Tribal conflicts, ethnic instability, and

Migration movements are movements of people from their countries of origin to others that may be permanent or temporary.

• The movement from the place of origin to a destination is called emigration. The person who performs it is an emigrant.
• In the place of destination, the arrival of people from other countries receives the name of immigration. People arriving are called immigrants.

The difference between immigrants and emigrants in a region is net migration. Immigrants, as they provide an effective increase, add to the total population, while emigrants who leave must be subtracted.

Net migration = Immigration - Emigration

• If the number of immigrants is higher than that of emigrants, net migration is positive and the population increases.
• If the

Tourist Areas in Spain

Importance of tourism: Tourism is a major economic driver for Spain, offsetting the balance of payments deficit. The tourism boom began in the mid-1950s, and the number of visitors has grown steadily since. Today, the Spanish economy is heavily reliant on tourism, with revenues equivalent to 30% of total exports. Without tourism, the country's economic growth would be significantly lower.

Factors in Spanish Tourism Development

Spain has always held a certain exotic appeal for educated Europeans, reinforced by its rich Arab culture, castles, and historical sites. Today, the attraction to Spain is mainly due to its climate, with dry summers, high temperatures, and abundant sunny days. The long coastline, scenic beauty, wealth...

Key Demographic Concepts

• Demographic Transition: The passage from an ancient demographic regime characterized by high birth and mortality rates to a modern one with low birth and mortality rates.
• Marriage Rate: The number of marriages that occur for every thousand inhabitants in a given year.
• Fertility Rate: The ratio between the number of births and the number of women of childbearing age (15-49 years).
• Infant Mortality Rate: The number of children under 1 year who died per 1,000 live births in a year.

Population Evolution in Castile and León

The capacity of the Douro Valley farming brought early human occupation to the territory. In the era of Rome, the landholding was quite intense. The repopulation of medieval times determined the structure... Continue reading "Demographic Trends in Castile and León" »

The Second Invasion of Europe

In Europe, the mid-9th and 10th centuries were marked by insecurity and division. The main groups involved were:

• Vikings: Originating from Scandinavia, they were fierce warriors who provoked great fear and panic.
• Magyars: Coming from the Asian steppes, they established themselves in Eastern Europe, where they formed the Kingdom of Hungary.
• Saracens: Muslim pirates who carried out many raids along the European Mediterranean coasts.

The Emergence of the Feudal System

This situation resulted in the emergence of feudalism, a social system with the following characteristics:

1. Every great noble achieved total mastery of their lands.
2. The primary nobles accepted the King through a pact called vassalage.
3. In turn, the nobles who were

1. Conquest of Al-Andalus and the Independent Emirate

In 711, the Visigoths suffered a civil war between Don Rodrigo and the relatives of the former king. The latter requested assistance from Muslim forces. General Tariq ibn Ziyad crossed the Strait of Gibraltar with his troops and defeated the army of Don Rodrigo at the Battle of Guadalete in Andalusia.

The invaders met little opposition, as the Visigoth nobility was divided and the general population remained indifferent. The Muslims conquered almost the entire peninsula, naming the territory Al-Andalus, and ruled the region for nearly 800 years.

Al-Andalus was initially governed by an emir or governor under the Caliph of Damascus, with Córdoba serving as the capital.

Industrial Location in Spain

Spanish industries are primarily located in the periphery, with the notable exception of Madrid. This distribution is driven by several factors, including:

• Subsoil wealth in coastal areas.
• High population density.
• Historical industrial planning by state institutions.
• Ease of communication and strategic policy decisions.

Historical Evolution of Industrial Location

Historically, cottage industries were situated in rural areas, as they relied heavily on natural resources, river networks, roads, and ports.

Early Industrialization

At the onset of industrialization, the first major hubs emerged in two areas:

• The Atlantic Coast: Specifically Guipúzcoa and Vizcaya.
• Catalonia: Which exhibited a high level of industrialization.

In Catalonia,... Continue reading "Industrial Location in Spain: Historical Evolution and Patterns" »

The Discovery of America: A Turning Point

The arrival of Christopher Columbus in America in 1492 marked one of the most pivotal events in European history, profoundly shaping the political, social, and economic landscape for centuries to come.

Motivations for Exploration

• The increasing difficulties faced by the Byzantine Empire, which eventually fell with the capture of Constantinople by the Turks in 1453, forced Western Europeans to seek alternative trade routes to Asia.
• By the late fifteenth century, it was clear that the Portuguese had surpassed the Spaniards in the race for spices and precious metals, thanks to their established dominance along the West African coast.

Columbus's Proposal and Voyage

At this time, Christopher Columbus, who had... Continue reading "The Age of Discovery: Columbus, Tordesillas, and Global Impact" »
