From a city, it accounts for the composition of its: in Barcelona that it increases slightly (it reaches 1.7 million people) due to the arrival of migrants, which are increasingly weight (the population with foreign nationality is 26.4%), and only 45% of the inhabitants are born in the city. But there are other exciting chapters to analyze a city: such as homes and its composition. And just as this section shows how in Barcelona, it earns weight the unipersonal homes. In reading on January 1 of this year, they are 31.6% of the total (215,153 homes). It is lower, 28%.
In these homes of a single person, a phenomenon that the head of the Department of Data and Dissemination, María Jesús Calvo describes as “solid, after having grown a lot in recent years”, women are a baggy majority (61%, partly because they live more, but it is not the only reason), compared to 39% of men. “It is a recurring feature in many territorial areas: how much more developed the welfare state is, the more possibilities there is to live alone. And how much bigger is the incorporation of women into the labor market, the less dependent the men are, and the more they choose to live alone,” says the report The population of Barcelona in 2025published this Saturday by the.
“Apart from aspects such as autonomy or intimacy, the increase in life expectancy (superior among women) and the hatching of telecommunications play in favor of the expansion of the unipersonal households of the two sexes,” adds the work. In the last 28 years, the distance between the two groups has shortened Calvo, and the percentage of households with a single man has significantly increased, 23%. Beyond the unipersonal homes, those of two people are 29% of the total in the city; and those of three and four people, 21%.
Another reality that shows the data of the homes is that for almost three decades they do not stop increasing households, while the number of people living on each floor falls. Since 1997, homes have grown by almost 100,000, while the occupation has fallen from 2.7 people per home to 2.48. Although eye, for two years the figure increases slightly, an explanation that will have to look for in future.
The population grows up to 1,732,066 neighbors
In global, the reading of the Padrón de Barcelona to January 1 shows, synthesizes María Jesús Calvo, which “the trends of recent years are consolidated, but slow down: the population continues to grow, but at a lower pace, and the weight of the foreign population grows, but also more slowly”. The population of Barcelona is 1,732,066 neighbors, 30,000 people more than a year ago (1.7% more) and the highest figure in 40 years. Birth and mortality have stopped the rhythm of descent, and and emigration have stabilized. The average age is 44.4 years, with a life expectancy between 85 and 86 years women, and 80 men. If the neighborhoods are observed, the population has grown by 70 of the 73. and grows in a remarkable way in the clota (which reaches a thousand neighbors) and attracts new registrations.
Centenary persons (1,104 of which 84% are women) and the academic level of those over 16, who in 37% are university students or have professional training studies of higher degree. By birthplace, Barcelona continues to lose native population, born in the city. In this sense, yes, this 2025 those born in the city are only 45%. Of those born abroad, the countries of origin with more weight are Argentina, Colombia and Peru. And by nationalities, 26.4% of the Barcelona population has foreign nationality. In this order, the most numerous are the Italian (which is born in Italy, Argentina and Uruguay), Colombian, Pakistani, China and Peruvian. In total there are 182 nationalities, after two incorporations: Santa Lucía and East Timor.
