Barcelona, 
Venezuela
674,757 people lived in Barcelona in 2025. It is the 805th largest of the world's 12,138 cities, and the 6th largest in Venezuela.
That figure counts the whole built-up area, not the area Barcelona governs, so it may be far from the number the city publishes about itself. How the UN measures a city.

How Barcelona grew
Where Barcelona had 10 people in 1975, it had 28.4 in 2025.
On the UN's projection it will have 785,399 people in 2050. It passed 250,000 people between 1975 and 1980.
projected (after 2025) · how sure the UN is: high moderate low
How to read this: each column is one of the UN's five-yearly estimates, 1975 through 2050, and taller means more people. Where a column is hatched the year has not happened yet. The strip under the columns is the UN's own confidence in each figure, palest where it is least sure; where it is blank the city was not on the list at all.

Barcelona through your family’s years
Put in the years your family were born. You’ll see how many people lived in Barcelona in each of those years, and when each of them turned 30.
Venezuela · every city · 2025
Where it is
How to read this: Venezuela and its 69 cities in 2025, each a dot whose area is its number of people (the largest is Caracas). Barcelona is ringed, in colour; the other cities are grey. Neighbouring countries are outlines.
Area and built-up land · km²
How much land it covers
In 2025, Barcelona covered 143 km², and buildings, roads and other built-up land covered 29 km² of it. That is 42 m² of built-up land for each person, about a square 7 by 7 metres. Since 1975, its built-up land has grown by 92%, and its people are 2.8 times as many.
How to read this: each pale square is the city's whole area, the strong square inside it the part that is built on; one scale for all three, so a bigger square is more land. Hatched is the UN's projection.
Of every 100 people in Venezuela
Its share of Venezuela
Of every 100 people in Venezuela in 2025, 2 lived in Barcelona, which is 674,757 people.
How to read this: 100 squares stand for everyone in Venezuela, one square for every 100th person. Count the coloured ones and you have Barcelona's share; the grey remainder live somewhere else in the country.

How to read this: names are in order of size, the leading number being each city's rank among all 12,138 in 2025; the bars share a scale within a list. A jump in the ranks means a city under 300,000 people, which is not given a page here.
Apparatus
Sources and method
The figures for Barcelona are the UN's own, at five-year steps: an estimate for each of 1975 to 2025, then projection to 2050. Projected years are drawn hatched, and the UN publishes no range of uncertainty for a city. What a city means here, how the UN measures one, and why that number can differ from the one Barcelona publishes about itself: how the figures here are put together.
