Explanations:The United Nations (UN) regularly publishes data on the world's most populous cities, which is a critical piece of information for understanding global urbanization trends. This data is often used in various competitive examinations to test candidates' knowledge of global demographics and urban population sizes.
In 2018, the UN released data that ranked the world's most populous cities based on their urban population. The ranking is determined by the number of people living within the city limits and its immediate urban area. This data is important for urban planners, policymakers, and researchers who study population dynamics and urban development.
Mumbai, the capital city of Maharashtra in India, is a major urban center with a large population. According to the UN data from 2018, Mumbai was ranked as the seventh most populous city in the world. This ranking is based on the total number of people living in the city and its surrounding urban areas, which includes the metropolitan region.
The ranking of cities can change over time due to various factors such as population growth, urban expansion, and changes in administrative boundaries. Therefore, it is essential to refer to the most recent data to get an accurate understanding of the current ranking. In the context of the question, the UN data from 2018 is the relevant source, and it clearly indicates that Mumbai was the seventh most populous city in the world at that time.
Understanding the ranking of cities like Mumbai is important for several reasons. It helps in assessing the scale of urban challenges such as housing, transportation, and public services. It also provides insights into the economic and social dynamics of these cities, which can be crucial for policy-making and urban planning.
It is worth noting that the ranking of cities can vary depending on the criteria used for measurement. For example, some rankings might consider the entire metropolitan area, while others might focus only on the city proper. Therefore, it is important to understand the specific criteria used in the UN data to interpret the ranking accurately.
In summary, the UN data from 2018 indicated that Mumbai was the seventh most populous city in the world, based on its urban population size. This ranking is a reflection of the city's significant population and its status as a major urban center in India and globally.
