La Unión, Cartago
La Unión is a canton in the province of Cartago, Costa Rica. As a canton, it helps explain the country at a closer scale than the province: local government, communities, services, everyday routes, landscape, and belonging. A province explains a region; a canton brings the reader closer to real life, where people study, work, shop, celebrate, travel, and say “I am from here.”
Short answer
La Unión belongs to Cartago. It is a close-scale canton, with neighborhoods, services, and routes tightly connected. Its value in this guide is to locate a concrete part of Costa Rican territory and connect it with the province it belongs to.

Location within Costa Rica
To understand La Unión, start with its province: Cartago. Cartago is known as a province associated with history, religious tradition, agriculture, and mountain landscapes, and each canton adds a different piece to that territorial reading. In Cartago, cantons are read through history, cool weather, highland agriculture, religious tradition, industry, and roads toward Turrialba. In that whole, La Unión works as a specific entrance into the human map of the province: not only an administrative name, but a combination of roads, population centers, landscape, services, and local memory.
Population, territory, and scale
La Unión has 99.539 people, according to INEC’s 2022 Population and Housing Estimate. Its land area is 44,2 km². That equals an approximate density of 2 252 people per km², useful for reading whether the canton feels urban, rural, dispersed, or mixed. The number does not say everything, but it helps: a small and dense canton is often organized around neighborhoods, commerce, transport, and nearby services; a large canton often depends more on routes, distances, districts, productive activities, and relationships with other zones.
Local history and everyday role
The history of a canton almost never fits into a single date. It is made of opened roads, families arriving, farms changing crops, schools, churches, plazas, small stores, festivals, soccer teams, buses, bridges, and place names people recognize before seeing them written. La Unión should be read that way: as a local government unit, but also as shared memory. Its municipality, districts, and communities form a scale where Costa Rica stops being only a national idea and becomes neighborhood conversation, municipal paperwork, market day, school, playing field, and daily route.
Economy, work, and everyday life
The economy of La Unión is best understood in relation to Cartago. Some cantons lean more on commerce, services, education, health care, technology, or metropolitan jobs; others on agriculture, cattle, tourism, fishing, ports, industry, or conservation. In every case, the canton matters because it organizes everyday life: where people work, where they shop, which routes they use, which products circulate, and how family life mixes with public life. Reading La Unión carefully helps show that Costa Rica does not operate only through national institutions, but through a network of municipalities and communities.
Landscape, identity, and belonging
The landscape of La Unión may be urban, rural, mountainous, coastal, agricultural, commercial, or a mix of several things. What matters is that landscape produces identity. The way people speak about a place changes when mist, heat, beach, coffee fields, roads, rivers, ports, farms, universities, markets, or mountains are nearby. That is why a canton page should not be only a data card. It should help answer practical questions: where it is, which province it belongs to, how it connects with other places, and why its name appears in conversations about Costa Rica.
How to read this canton
A good way to read La Unión is through three layers. First, as part of Cartago; second, as a local government unit with a code, area, and its own communities; third, as a place lived by people who are not defined only by statistics. Data helps organize the page, but identity comes from experience: daily routes, food, accents, festivals, landscapes, and family stories.
Summary for understanding La Unión
To answer what La Unión is, it helps to say it simply: it is a canton of Cartago, with municipal government, defined territory, its own communities, and a direct relationship with daily life in the province. That short answer helps, but it does not replace the fuller reading. A canton is also human scale: the place where public decisions become sidewalks, roads, permits, parks, markets, waste collection, cultural activities, and nearby services.
