In 2024, approximately 11.9 million people lived in São Paulo, making it the largest municipality in Brazil and one of the most populous cities in the world. The homonymous state of São Paulo was also the most populous federal entity in the country. Brazil's cities Brazil is home to two large metropolises: São Paulo with close to 11.9 million inhabitants, and Rio de Janeiro with around 6.7 million inhabitants. It also contains a number of smaller but well-known cities, such as Brasília, Salvador, Belo Horizonte, and many others, which report between 2 and 3 million inhabitants each. As a result, the country's population is primarily urban, with nearly 88 percent of inhabitants living in cities. While smaller than some of the other cities, Brasília was chosen to be the capital because of its relatively central location. The city is also well-known for its modernist architecture and utopian city plan, which is quite controversial - criticized by many and praised by others. Sports venues capitals A number of Brazil’s medium-sized and large cities were chosen as venues for the 2014 World Cup, and the 2015 Summer Olympics also took place in Rio de Janeiro. Both of these events required large sums of money to support infrastructure and enhance mobility within a number of different cities across the country. Billions of dollars were spent on the 2014 World Cup, which went primarily to stadium construction and renovation but also to a number of different mobility projects. Other short-term spending on infrastructure for the World Cup and the Rio Olympic Games was estimated at 50 billion U.S. dollars. While these events have poured a lot of money into urban infrastructure, a number of social and economic problems within the country remain unsolved.

In 2025, approximately 23 million people lived in the São Paulo metropolitan area, making it the biggest in Latin America and the Caribbean and the sixth most populated in the world. The homonymous state of São Paulo was also the most populous federal entity in the country. The second place for the region was Mexico City with 22.75 million inhabitants. Brazil's cities Brazil is home to two large metropolises, only counting the population within the city limits, São Paulo had approximately 11.45 million inhabitants, and Rio de Janeiro around 6.21 million inhabitants. It also contains a number of smaller, but well known cities such as Brasília, Salvador, Belo Horizonte and many others, which report between 2 and 3 million inhabitants each. As a result, the country's population is primarily urban, with nearly 88 percent of inhabitants living in cities. Mexico City Mexico City's metropolitan area ranks sevenths in the ranking of most populated cities in the world. Founded over the Aztec city of Tenochtitlan in 1521 after the Spanish conquest as the capital of the Viceroyalty of New Spain, the city still stands as one of the most important in Latin America. Nevertheless, the preeminent economic, political, and cultural position of Mexico City has not prevented the metropolis from suffering the problems affecting the rest of the country, namely, inequality and violence. Only in 2023, the city registered a crime incidence of 52,723 reported cases for every 100,000 inhabitants and around 24 percent of the population lived under the poverty line.

Smart City Platform Market Outlook

According to our latest research, the Global Smart City Platform market size was valued at $19.4 billion in 2024 and is projected to reach $83.7 billion by 2033, expanding at a robust CAGR of 17.8% during the forecast period of 2025–2033. One of the major factors fueling the growth of the Smart City Platform market globally is the rapid urbanization coupled with increasing government investments in smart infrastructure to enhance urban living standards. As cities worldwide face mounting pressures from population growth, resource constraints, and the need for sustainable development, smart city platforms are emerging as critical enablers for integrating digital technologies across transportation, energy, governance, and public safety sectors. These platforms help streamline urban operations, improve citizen engagement, and optimize resource utilization, thereby driving widespread adoption and market expansion.

Regional Outlook

North America continues to dominate the Smart City Platform market, accounting for the largest share of the global revenue in 2024, with an estimated market value exceeding $6.8 billion. This region’s leadership is underpinned by its mature technology ecosystem, early adoption of Internet of Things (IoT) solutions, and robust government initiatives such as the Smart Cities Challenge in the United States and Canada’s Smart Cities Plan. The presence of major technology companies and a strong focus on public-private partnerships have further accelerated the deployment of smart city platforms across metropolitan areas. Additionally, stringent regulations around energy efficiency, urban mobility, and public safety have encouraged cities to invest in integrated platforms, reinforcing North America’s preeminent position in the global market.

Asia Pacific is poised to be the fastest-growing region in the Smart City Platform market over the forecast period, projected to register an impressive CAGR of 21.2% from 2025 to 2033. This exceptional growth is attributed to rapid urbanization, significant investments in digital infrastructure, and ambitious smart city initiatives by countries such as China, India, Japan, and South Korea. Massive government funding, coupled with the proliferation of 5G networks and IoT devices, is propelling the adoption of smart city platforms across transportation, energy management, and public safety domains. Moreover, the region’s burgeoning population and rising demand for efficient urban services are driving municipalities to embrace digital transformation, making Asia Pacific a focal point for market expansion and innovation.

Emerging economies in Latin America, the Middle East, and Africa are witnessing a gradual yet steady uptake of Smart City Platform solutions, though growth is tempered by challenges such as limited funding, infrastructural bottlenecks, and regulatory uncertainties. While cities like Dubai, Riyadh, and São Paulo are making significant strides through pilot projects and regional collaborations, widespread adoption remains hindered by disparities in digital literacy, fragmented policy frameworks, and the high upfront costs associated with deploying integrated platforms. However, as international development agencies and private investors increasingly prioritize urban modernization in these regions, there is potential for accelerated growth, particularly in sectors like utilities management and environmental monitoring.
