Final answer:
Without additional information about what 'level 2' refers to, it's impracticable to provide an accurate population count. Globally, there are about 7.6 billion people as of 2019, with a projected increase in population. The population density varies significantly across different regions and urbanization levels.
Step-by-step explanation:
The question "Roughly how many people live on level 2?" appears to refer to a hypothetical scenario or a context that is not fully explained within the question.
To provide a comprehensive answer, we would need additional details about what 'level 2' refers to. However, discussing existing population data, we know that population density varies significantly across different regions and levels of urbanization. For example, in large cities, population density can be extremely high. Conversely, in rural or less developed areas, population density can be quite l
Considering the global context, approximately 7.6 billion people were alive as of September 2019, with growth projections suggesting this number could increase to 9 billion by 2050.
The distribution of population is uneven, with some countries like China and India each having more than a billion inhabitants. Poverty levels also vary widely, with significant portions of populations living on less than $1.90 to $10 per day, highlighting disparities in living standards.
If we attempt to contextualize 'level 2' as a metaphorical secondary stage of urbanization or development, the number of inhabitants would still depend on the specific details which have not been provided in the question. Accordingly, without additional clarification or context for 'level 2', providing an accurate population count is impracticable.
