Global Economic and Demographic Shifts: Commerce, Transport, and Population Dynamics

New Forms of Commercial and Consumer Spaces

The small business now faces competition from large retail chains and franchise networks. This concentration process is similar to what occurred in industry, banking, or the media.

This modern trade organization creates new landscapes, the best example of which is the supermarkets. In urban neighborhoods, these include:

• Hypermarkets: Large facilities belonging to a single company.
• Shopping Centers: Complexes that house a large number of specialty stores.
• Retail Parks: Areas featuring several hypermarkets and entertainment centers.

Transport Developments and Evolution

Historical Evolution of Transport

Transport systems have constantly evolved through the constant introduction of technological improvements over the years.

• Pre-Industrial Era: Exchanges were few and generally over short distances, due to rudimentary transport systems.
• First Industrial Revolution: Led to a revolution in transport with the appearance of rail and steamship.
• Second Industrial Revolution: Contributed two new means of transportation: the automobile and the airplane.
• Third Industrial Revolution: Focused on the transfer and transport of information, thanks to the development of communication networks, computers, and related technologies.

Current Transport Systems

Modern transport systems include:

• Transport by rail
• Road transport
• Sea transport
• Air transport
• Intermodal transport

Key Demographic Indicators and Population Dynamics

Birth Rate

The birth rate is the number of births in relation with the total population of the same territory over a year.

• Developed countries generally have low birth rates.
• Developing countries are experiencing a reduction in the birth rate.

Calculating the Birth Rate

(Births x 1000)
_______________
Total Population

Mortality Rate

The mortality rate relates the number of deaths in a year in a territory with the total population.

A higher level of development, improved nutrition, and better health care cause a decrease in mortality.

The most developed countries show a higher degree of aging, few births, and very high life expectancy.

Calculation of Mortality Rate

(Deaths x 1000)
_______________
Number of Inhabitants

Natural Growth Rate

It is the difference between the number of births and deaths.

• Developing countries have a high natural growth because they have a high birth rate relative to mortality.
• Developed countries have weak natural growth because the birth rate is so low that it almost equals mortality.

Calculation of the Natural Growth Rate

Birth Rate - Mortality Rate

Migration Today

Developed countries receive significant numbers of immigrants from countries with a lesser degree of development.

Key destinations include:

• The U.S. stands out
• The European Union
• Spain

Migration originating in developing countries occurs for different reasons:

• Due to oil resources and increasing degrees of industrialization.
• Wars cause large migrations to more developed countries.
• The shift from rural to urban areas (internal migration).

Aging Rate

Calculation of the Aging Rate

(Percentage of Elderly Population / Percentage of Young Population) x 100
