In 1800, the population of Portugal was estimated to be approximately 2.8 million; a figure that would see gradual growth throughout the 19th century. During this time, Portugal experienced a series of political and military challenges, including an invasion by Napoleonic France, the cessation of Brazil (it's largest colony), and a civil war caused by royal succession; nonetheless, Portugal remained an international power throughout the 1800s, with significant spheres of influence on all continents. 20th century At the turn of the 20th century, Portugal's international standing began to diminish, and its weakening position in Africa initiated a wave of civil unrest in the metropole. In 1908, following a period of political instability, King Carlos I and his heir were assassinated in Lisbon, and the 5 October 1910 Revolution permanently brought an end to the monarchy. This, however, did not end the political instability, which was further exacerbated by the impacts of the First World War and Spanish Flu pandemic (which, combined, resulted in the deaths of more than 220,000 Portuguese people). Portugal would then experience a rapid population gain following the establishment of the Second Republic (Estado Novo) in 1933, under the 34 year reign of António de Oliveira Salazar, which would see Portugal’s currency stabilized and significant economic growth lasting until the 1960s. However, Portugal’s population would decline in the early 1960s, as escalating colonial wars overseas, combined with increasing political instability at home would see many citizens emigrating elsewhere in Europe; particularly youths attempting to avoid the country’s military draft. Growth would largely resume following the end of the dictatorship with the Carnation Revolution of 1974, as many Portuguese migrants in the now independent colonies would return to Europe. Recent decades While growth would slow (and decline slightly) amidst economic troubles in the 1980s, Portugal’s population generally increased until 2008, when it peaked at 10.6 million people. From 2008 until today, a combination of the long term impacts of the 2008 financial crisis and declining fertility rates have resulted in a steady drop in the country’s population. As a result, in 2020, Portugal is estimated to have fallen to 10.2 million people, although it is also regarded as one of the most stable, peaceful and democratic countries in the world.

This statistic displays the age of the population of Portugal in 2015, with forecasts for 2025 and 2035. In 2015, the largest Portuguese age group were those aged between 15 and 34, at over *** million people. By 2035 the number of people aged 15-34 is forecasted to decline to **** million, while there are anticipated to be **** million people aged over 65, the largest cohort in this year.

The total population of Portugal stood at approximately 10.67 million people in 2024. Between 1980 and 2024, the total population rose by around 900 thousand people, though the increase followed an uneven trajectory rather than a consistent upward trend. The total population is forecast to decline by about 80 thousand people from 2024 to 2030, fluctuating as it trends downward.This indicator describes the total population in the country at hand. This total population of the country consists of all persons falling within the scope of the census.

Population aged 0-14 years of Portugal decreased by 0.84% from 13.0 % in 2022 to 12.9 % in 2023. Since the 1.11% decline in 2013, population aged 0-14 years slumped by 12.75% in 2023. Population between the ages 0 to 14 as a percentage of the total population. Population is based on the de facto definition of population.

Portugal: Rural population, percent of total population: The latest value from 2023 is 32.09 percent, a decline from 32.62 percent in 2022. In comparison, the world average is 38.64 percent, based on data from 196 countries. Historically, the average for Portugal from 1960 to 2023 is 49.94 percent. The minimum value, 32.09 percent, was reached in 2023 while the maximum of 65.04 percent was recorded in 1960.

Despite some considerable fluctuation throughout this period, there has been an overall increase of around 0.5 million foreign-born residents in Portugal. The peak has been in 2023 at approximately 1.733 million foreign people.

This graph shows the population of Portugal from 1864 until 2020, by gender. Throughout this period the number of women has always outnumbered men since 1864. In the first entry the number of men was 2 million people, and the number of women was 2.2 million. We can see that this difference remained until the turn of the twentieth century when the gap became broader. From 1910 until 1920 the population of Portugal experienced limited growth as a result of food shortages and influenza, and women appear to have been more heavily affected by this than men.

From this point onwards the number of men and women follow a similar trend, although the growth and decline rate for men fluctuates more than women. The population falls in the 1960s, as many Portuguese people migrated in search of work, and the number of men fell faster than the number of women during this time. As time progresses the difference in the number of men and women decreases, until 2005 where the number of men starts to decrease before the number of women does. This decline came as many Portuguese people emigrated in search of work abroad, and the number of men falls faster than the number of men, as men are statistically more likely to migrate in search of work than women.

In 2023, Portugal had ***** million foreign residents. Men numbered *******, while women were *******. The nationality that is most present within the Portuguese foreign population is the Brazilian with ******* residents currently living in the country. The rise in foreign residents in Portugal In 2023, there was an increase of **** percent in registered foreign residents in Portugal compared to the previous year. The annual growth in foreign residents was interrupted in 2020, when it went from **** percent, registered in 2019, to **** percent. Despite this temporary decline in registered foreigners, the foreign-born population in Portugal has not declined since 2014. In 2023, there were **** million foreigners residing in the country. Refugees and asylum-seekers in Portugal Since 2013, the number of refugees in Portugal has continuously increased, going from *** to over ***** in 2021. However, the amount of asylum-seekers dropped in 2017, when it went from *** to just **, due to multiple socio-political circumstances in the countries of origin, but also in other nations of destination. By 2021, there were more than ***** persons seeking asylum in Portugal. Afghanistan was the main country of nationality of these individuals, which amounted to *** in 2022, followed by India and, at a large distance, Ukraine.

Portugal: Catholic Christians as percent of the total population: The latest value from 2013 is 85.2 percent, a decline from 85.6 percent in 2012. In comparison, the world average is 43.2 percent, based on data from 84 countries. Historically, the average for Portugal from 1960 to 2013 is 92.6 percent. The minimum value, 85.2 percent, was reached in 2013 while the maximum of 96.6 percent was recorded in 1960.

Portugal: Poverty, percent of population: The latest value from 2021 is 16.4 percent, a decline from 18.4 percent in 2020. In comparison, the world average is 22.31 percent, based on data from 66 countries. Historically, the average for Portugal from 2003 to 2021 is 18.27 percent. The minimum value, 16.2 percent, was reached in 2019 while the maximum of 20.4 percent was recorded in 2003.

The history of modern Brazil begins in the year 1500 when Pedro Álvares Cabral arrived with a small fleet and claimed the land for the Portuguese Empire. With the Treaty of Torsedillas in 1494, Spain and Portugal agreed to split the New World peacefully, thus allowing Portugal to take control of the area with little competition from other European powers. As the Portuguese did not arrive with large numbers, and the indigenous population was overwhelmed with disease, large numbers of African slaves were transported across the Atlantic and forced to harvest or mine Brazil's wealth of natural resources. These slaves were forced to work in sugar, coffee and rubber plantations and gold and diamond mines, which helped fund Portuguese expansion across the globe. In modern history, transatlantic slavery brought more Africans to Brazil than any other country in the world. This combination of European, African and indigenous peoples set the foundation for what has become one of the most ethnically diverse countries across the globe.

Independence and Monarchy By the early eighteenth century, Portugal had established control over most of modern-day Brazil, and the population more than doubled in each half of the 1800s. The capital of the Portuguese empire was moved to Rio de Janeiro in 1808 (as Napoleon's forces moved closer towards Lisbon), making this the only time in European history where a capital was moved to another continent. The United Kingdom of Portugal, Brazil and the Algarves was established in 1815, and when the Portuguese monarchy and capital returned to Lisbon in 1821, the King's son, Dom Pedro, remained in Brazil as regent. The following year, Dom Pedro declared Brazil's independence, and within three years, most other major powers (including Portugal) recognized the Empire of Brazil as an independent monarchy and formed economic relations with it; this was a much more peaceful transition to independence than many of the ex-Spanish colonies in the Americas. Under the reign of Dom Pedro II, Brazil's political stability remained relatively intact, and the economy grew through its exportation of raw materials and economic alliances with Portugal and Britain. Despite pressure from political opponents, Pedro II abolished slavery in 1850 (as part of a trade agreement with Britain), and Brazil remained a powerful, stable and progressive nation under Pedro II's leadership, in stark contrast to its South American neighbors. The booming economy also attracted millions of migrants from Europe and Asia around the turn of the twentieth century, which has had a profound impact on Brazil's demography and culture to this day.

The New Republic

Despite his popularity, King Pedro II was overthrown in a military coup in 1889, ending his 58 year reign and initiating six decades of political instability and economic difficulties. A series of military coups, failed attempts to restore stability, and the decline of Brazil's overseas influence contributed greatly to a weakened economy in the early 1900s. The 1930s saw the emergence of Getúlio Vargas, who ruled as a fascist dictator for two decades. Despite a growing economy and Brazil's alliance with the Allied Powers in the Second World War, the end of fascism in Europe weakened Vargas' position in Brazil, and he was eventually overthrown by the military, who then re-introduced democracy to Brazil in 1945. Vargas was then elected to power in 1951, and remained popular among the general public, however political opposition to his beliefs and methods led to his suicide in 1954. Further political instability ensued and a brutal, yet prosperous, military dictatorship took control in the 1960s and 1970s, but Brazil gradually returned to a democratic nation in the 1980s. Brazil's economic and political stability fluctuated over the subsequent four decades, and a corruption scandal in the 2010s saw the impeachment of President Dilma Rousseff. Despite all of this economic instability and political turmoil, Brazil is one of the world's largest economies and is sometimes seen as a potential superpower. The World Bank classifies it as a upper-middle income country and it has the largest share of global wealth in Latin America. It is the largest Lusophone (Portuguese-speaking), and sixth most populous country in the world, with a population of more than 210 million people.

Bird populations are declining globally with losses recorded in many European breeding birds. Habitat management measures have not resulted in a widespread reversal of these declines. We analysed national bird population trends from ten European countries (France, Hungary, Ireland, the Netherlands, Poland, Portugal, Spain, Sweden, Switzerland, and the UK) in relation to the species’ nesting strategy (‘ground-nesting' or ‘other’), Annex I designation (‘designated’ or ‘not designated’) and association with agricultural habitats for breeding (‘associated’ or ‘not associated’). For each country in our dataset, we also defined the following factors: farming intensity; predator community complexity; and predator control effort. Our results showed additive effects of nesting strategy, designation, and breeding habitats on the likelihood of population decline. Ground-nesting birds were 86% more likely to decline than birds with other nesting strategies. Annex I designated species of the Birds Directive were 50% less likely to decline than non-designated birds. Birds breeding primarily in agricultural habitats were more likely to decline than birds breeding in other habitats, interactively with farming intensity. Homogenous trends across Europe (i.e., trends in two or more countries that were either not declining in all countries or declining in all countries) indicate that the probability of population decline was related to nesting strategy and breeding habitat, with ground-nesting birds being 15.6 times more likely than other birds to have a declining trend across Europe, and birds nesting in agricultural habitat being 17.8 times more likely than birds nesting in other habitats to have a declining trend across Europe. Our results highlight a widespread challenge, therefore widespread instruments (e.g. legislation, economic policies, agri-environment schemes) will be required to reserve these declines. Ground-nesting species requirements can be complex and multiple strategies will be needed to restore populations including the development of predation management tools. Methods Many countries provide data to the Pan-European Common Bird Monitoring Scheme (PECBMS). We explored the PECBMS web page and the links included therein for each country, to identify if national data on population trends for each species could be obtained. Finally, we obtained national trends data for 10 countries, namely France (FR), Hungary (HU), Ireland (IE), the Netherlands (NL), Poland (PL), Portugal (PT), Spain (ES), Sweden (SE), Switzerland (CH) and the UK (UK). Specifically, common bird species trends in France were obtained from the monitoring programs coordinated by the Natural History Museum (http://www.vigienature.fr/fr/resultats-especes-3367). These data provided a 20-year trend (1998-2018) for each species. Hungary data from the Monitoring Centre of the Hungarian Ornithological and Nature Conservation Association were available at https://mmm.mme.hu/charts/trends and provided species trends for the period 1999-2021. Data from Ireland were available at https://www.npws.ie/sites/default/files/publications/pdf/IWM115.pdf and provided trends for 1998-2016 for each species. Netherlands data were obtained from the monitoring programs carried out by SOVON, the Dutch Centre for Field Ornithology (https://www.vogelwarte.ch/assets/files/publications/upload2019/Zustand%20der%20Vogelwelt%20in%20der%20Schweiz_Bericht%202019_E_low.pdf). These data provided species trends from 1990 to 2016. Polish data were obtained from https://monitoringptakow.gios.gov.pl/database.html, and provided trends for each species for the period 2000-2019. Portuguese data (based on the program organised by the Sociedade Portuguesa para o Estudo das Aves, SPEA) were obtained from https://www.spea.pt/wp-content/uploads/2021/06/relatorio_cac_2021_vf3.pdf, as long-term (2004-2020) trends for each species. Data from Spain were obtained from the monitoring programs conducted by SEO/Birdlife (https://seo.org/boletin/seguimiento/boletin/2018/html5forpc.html?page=0), consisting of long-term trends (1998-2018) for each species. Data from Sweden, showing 1998-2022 trends for each species, were obtained from http://www.fageltaxering.lu.se/resultat/trender. Swiss data were obtained from the monitoring programs carried out by Vogelwarte, the Swiss Ornithological Institute (https://www.vogelwarte.ch/assets/files/projekte/entwicklung/zustandsbericht%202019/Zustandsbericht%202019_e_low.pdf) and consisted of 1990-2018 trends for each species. The UK data were obtained through monitoring programs at the British Trust of Ornithology (https://www.bto.org/our-science/publications/birdtrends/2020/species), providing long-term (1994-2020) trends for each species. In all cases, trends for each species were categorised according to European Bird Census Council (EBCC) definitions (see https://pecbms.info/methods/pecbms-methods/1-national-species-indices-and-trends/1-2-production-of-national-indices-and-trends/trend-interpretation-and-classification) as ‘important decline’, ‘moderate decline’, ‘stable’, ‘moderate increase’, ‘marked increase’ or ‘uncertain. We regrouped the categories as ‘decline’ (either important or moderate) or ‘no decline’, (stability, moderate or important increase, or uncertain trends) to obtain a binomial variable describing the decline probability of a given species in each country.

The annual population growth in Andorra decreased to 1.43 percent compared to the previous year. This decrease was preceded by an increase in population growth.Annual population growth refers to the change in the population over time, and is affected by factors such as fertility, mortality, and migration.Find more key insights for the annual population growth in countries like Spain and Portugal.

In 2025, 24.7 percent of the total population in Italy is estimated to be 65 years and older. According to data, the share of elderly people in the Italian society has been growing constantly since 2009. Consequently, the share of young population experienced a decrease in the last years. As a result, the average age of Italians has risen. In 2011, it was 43.6 years, whereas in 2024 it was estimated to be 46.8 years. The oldest country in Europe Italy and Portugal are the European countries with the largest percentage of elderly citizens. In 2024, 24 percent of the total population was aged 65 years and older. Bulgaria and Finland followed in the ranking, while Azerbaijan had the lowest share of elder population, less than ten percent. An increasingly longer lifespan might provide an explanation for such a high share of citizens over 65 years in Italy. The Republic ranks among the countries with the highest life expectancy worldwide. In Europe, only people in Switzerland and Spain can expect to live longer. Fewer babies than ever The share of young people is getting slimmer, not only because the elderly are living longer than ever before. In fact, Italians are having fewer children compared to previous years. The birth rate in the country has been constantly decreasing: in 2024, only 6.3 babies were born per 1,000 inhabitants, three children less than in 2010. In the south of Italy, in 2023 the birth rate stood at 6.7 infants per 1,000 inhabitants, whereas in central Italy this figure reached only 5.8, the highest and lowest rates in the country, respectively.
