2019 Population by County and Sub-County

The dataset details population figures, gender distribution, household counts, and land area for counties and sub-counties.
It includes metrics like average household size and population density, offering insights into living conditions and land use.
The total population for the entire dataset (47,564,296) is present as the first row, with null values for county and sub_county, indicating an aggregate national total.
There's a significant range in population density, from 0 to 68,941, suggesting highly varied urbanization or land use across areas.
The 'intersex' column has 11% null values, and 'sub_county' has 12% nulls, indicating incomplete demographic or geographical data for some entries.
The maximum values for male, female, and population are extremely high, corresponding to the national aggregate row, which acts as an outlier compared to individual county/sub-county data.
What is the average population density across all sub-counties, excluding the national aggregate?
Which counties have the highest average household size?
How does the male-to-female ratio vary between urban (high density) and rural (low density) sub-counties?
