A case, step by step: “Who lives far from a CAP?” in Barcelona

1Choose the question
In the Barcelona area, the views drawer and Health. The area can also be the whole AMB, a district or a drawn area.
2Read the answer
“In one sentence”, the median and the residents and older people more than 500 m from a CAP, always next to the AMB figure.
3Go down to the building
One click gives the address and that building’s distance to the nearest CAP, and compares it with the section, Barcelona and the AMB.
4Take it with you
A PNG with title, legend, sources and date, or a CSV per section, ready for the report or the plenary.

Case 1 · Public health

Older people far from a CAP

For: health and older-people services of town halls, regional health planning.

“Who lives far from a CAP?” and, crossing data, “Where do older people live far from primary care?”

What you see: Each building takes the colour of its straight-line distance to the nearest CAP. The panel gives the median of the sections (Barcelona 429 m, AMB 421 m), the percentage of residents and of older people in sections more than 500 m away (Barcelona 34.3% and 34.9%; AMB 37.3% and 36.6%) and the ranking by district. A click on a building opens its card for this view.
Views and tools: Views › Health · Explore › Cross · building card · area card in PDF
Limits: Straight-line distance, not walking time. Facilities catalogue of October 2026; INE 2025 census sections.

Building card for the view

With the Health view, a click on a building opens its card: the address, the distance to the nearest CAP and the reference for Barcelona and for the AMB.

Card for the building at Provença street 257 with the Health view: 459 metres to the nearest CAP, 547 metres to the section’s representative point, 19.8% older people in the section and the medians for Barcelona and the AMB. — **Building card: Provença 257**
With the Health view, the building card gives the straight-line distance to the nearest CAP (459 m) and compares it with the section and with Barcelona.

Case 2 · Education

Children far from school

For: education departments, education consortia and school planning.

“Who lives far from a primary school?” and “Where do many children live far from a primary school?”

What you see: The distance from each building to the nearest primary school, where most children live (Children view) and schools, secondary schools and nurseries painted on their own building.
Views and tools: Views › Education, Children and Facilities · Explore › Cross (children × school)
Limits: Straight line; the catalogue gives neither places nor an official catchment area.

Education view in Gràcia: buildings in greens and ochres by distance to the nearest primary school and educational centres in magenta, with the figures in the panel. — **Education**
Distance from each building to the nearest primary school; schools and secondary schools painted on their own building.

Case 3 · Heat and emergencies

Climate shelters nearby

For: public health, environment and emergencies.

“Who has a climate shelter far away?” and “Where do older people live far from a climate shelter?”

What you see: The distance from each building to the nearest climate shelter; crossings of older people and of income with that distance; urban green, access to parks and street trees. The facilities simulator tests a new shelter and counts who is far away before and after.
Views and tools: Views › Heat, Urban green and Park nearby · Explore › Cross · Planning › Facilities simulator
Limits: The scenario is hypothetical and does not change the official data; shelters according to the published catalogue.

Heat view in Gràcia and the Eixample: buildings coloured by distance to the nearest climate shelter and the shelters as dots, with the median in the panel. — **Heat and climate shelters**
Distance from each building to the nearest climate shelter, with the shelters marked.

Case 4 · Mobility

Public transport, street by street

For: transport operators and authorities, municipal mobility services.

What you see: Scheduled bus trips per hour on each street segment (TMB and AMB combined) with the day profile; rail frequency; the focus of a line with its stops; AMB bus trails by timetable; commuting from the 2023 census and live traffic in Barcelona.
Views and tools: Views › Bus frequency, Rail frequency, Commuting and Traffic · line focus · Planning › Stops and lines simulator
Limits: Scheduled supply on a weekday, not passengers or vehicle positions; the trails are the timetable; commuting counts people, not trips.

Line focus

A click on line H12 switches the city off and leaves only the line, with its colour and its stops; “Leave focus” restores it.

Commuting view: arcs towards Barcelona with thickness proportional to the people who work there and rings with the percentage who work in their own municipality. — **Commuting**
Where those who live in each municipality work and where those who work there come from, according to the 2023 census. These are people, not trips.
