Livelihood refers to the means, capabilities, and resources that individuals or communities utilize to make a living, secure their basic needs, and sustain themselves over time. It is a multidimensional concept encompassing not just income or employment but also the broader social, economic, and environmental factors that contribute to well-being and resilience. In the context of sustainable development and smart cities, livelihoods are closely tied to urban planning, economic opportunities, social inclusion, and environmental sustainability. A sustainable livelihood ensures that people can meet their current needs without compromising the ability of future generations to meet theirs, while also enhancing resilience against shocks, stresses, and vulnerabilities such as economic fluctuations, climate change, and social inequalities. A livelihood is not simply defined by the occupation or income of an individual; it is a composite of various resources, skills, and strategies that together allow people to sustain themselves. In smart cities, the concept of livelihood expands to include digital and knowledge-based opportunities, access to urban infrastructure, mobility, and sustainable economic practices. Modern urban planning aims to integrate livelihood security with environmental management, social equity, and technological innovation. This holistic approach ensures that citizens can engage in productive activities while benefiting from improved health, education, social security, and sustainable resource use. The livelihood profile is an analytical tool used to understand the structure, characteristics, and sustainability of livelihoods within a community, neighborhood, or city. It provides detailed information about the ways people earn a living, the resources they depend on, and the vulnerabilities they face. By examining livelihood profiles, policymakers, urban planners, and development professionals can identify gaps, risks, and opportunities for enhancing economic, social, and environmental outcomes. In smart cities, livelihood profiles are crucial for designing inclusive economic policies, promoting local entrepreneurship, ensuring access to quality jobs, and aligning technological infrastructure with community needs. Livelihood profiles also help in mapping the interactions between urban and rural economies, the informal and formal sectors, and traditional and emerging industries, which are essential for building resilient urban economies. Livelihood profiles are composed of several interrelated components that together determine the sustainability and effectiveness of livelihoods. The first component is human capital, which includes the skills, knowledge, education, health, and labor capacity of individuals. In smart cities, human capital is enhanced through access to quality education, vocational training, digital literacy programs, and health services. Skilled human capital not only improves employability and productivity but also encourages innovation, entrepreneurship, and participation in
