The progressive or regressive pyramid It refers to a type of economy, social, cultural level, etc. that a country has with respect to its inhabitants. This pyramid is determined by two indices: the birth rate and the death rate.
Through the population pyramid, an analysis of the composition by age and sex of the population that a country has at a given time can be graphically determined.
Within a large group of pyramids are the rhythmic ones and, within these, there areprogressive and stationary pyramids.
Progressive pyramid
They are countries where the largest population is young. This is due to a high birth rate. The mortality levels are happening progressively. However, life expectancy is not high for long-lived people.
This type of pyramids is characteristic of the underdeveloped countries.
- Haiti
- Bolivia
- Cuba
- Mozambique
- Ivory Coast
- Angola
- Botswana
- Algeria
- Cameroon
- Republic of Cape Verde
Also, within this type of rhythmic pyramids are stable or stationary pyramids.
Stationary pyramid
This type of pyramids represent the Developing countries since there is already a birth control and a life expectancy greater than in the previous pyramid.
In terms of statistics, there is a similar number of young people as of older adults. It does not show significant natural growth or it is very scarce. This type of pyramid is considered to be an intermediate between the progressive and the regressive pyramid.

A country is considered to have an arrhythmic pyramid when it suffers (or has suffered in the recent period) some massive epidemic, wars, migrations, etc. This generates a very noticeable imbalance between the number of men and women.
Within this type of company, different types can be found:
Regressive pyramid
They are societies where both the death rate and the birth rate are very low. Faced with this type of society, the intervention of the state is essential to be able to provide a solution since, with this type of pyramids, society tends to disappear.
Immigrant reception policies or facilities for people with large families are mostly established
These pyramids can mostly be seen in developed countries since a birth control is carried out, although the long life expectancy is evaluated with a greater need for time.

- Australia
- Hong Kong
- Taiwan
- Singapore
Inverted pyramid
In these cases, there is a low birth rate. This turns out to be lower than the mortality rate. Therefore, societies with an inverted pyramid have a higher mortality rate than a birth rate, which would lead us to think about concern about the possible disappearance of that country. This type of pyramid is typical of very impoverished countries.
Examples of inverted pyramids: Spain, in particular the cities of Madrid and Barcelona.
Clarification: To date, there are no other countries with this type of pyramids. At least not statistically proven.
Anvil pyramid
It is the type of country where, after suffering some type of epidemic, war or emigration, the population indices as well as the natural gender indices have become unbalanced. For this reason, adjustments are made at the civil political level to prevent this type of pyramid from continuing for a long time.
Example: When Paraguay lost the Triple Alliance War, that country had almost no young male inhabitants. For this reason, a law was established in which men were allowed to marry more than one woman in order to repopulate that country.
What type of pyramid favors a country?
The pyramid that most favors a country is the regressive one because, although it has mortality rates and a certain birth control, it is the type of pyramid that has the longest life expectancy.
It also has a high rate of entry of young immigrants who come to the country in search of job opportunities or studies. Therefore, they are accessible (profitable) labor for the country.
What type of pyramid is the most disadvantageous to a country?
The pyramid that most disadvantages a country is the progressive one since they have a high birth rate, a very low life expectancy and, as a consequence of the aforementioned, a high death rate.
As mentioned above, this type of pyramid is observed in underdeveloped countries.
