4 factors effecting population density
demographic
Economics
Environment
Social
What is the general trend of population density in the UK
population is higher in the south
Highest/lowest population is the most dense in the south-east of England
Population density is much lower in the far north(Scotland) and the west (wales)- the more rural areas
2 positives of the chloropleth map (colour bloc)
Can locate data to location
Good visual impression of change over space
3 negatives of the chloropleth map
quantity is assumed to be the same throughout the polygon
False impression of abrupt change at boundaries
Difficult to distinguish between shades if too many are used
A positive of the dot density map
It is more accurate representation of spatial data
3 negatives of the dot density map
more complicated to construct
Difficult counting large number of dots to read data
Requires more ancillary data (e.g location of dots)
What is a recent population change in the UK
The north to south drift
What is the rural urban continuum
Urban areas are more densely packed than rural however urban areas vary greatly in terms of population density
Describe the CBD
Low permanent population density as residents are out-prices by commercial buildings for space
Describe the inner city
High-density housing (proximity to CBD, even previously industrial areas commonly gentrified into housing/flats (e.g Toronto waterfront)
Describe the Suburbs
Density decreasing reflects change to low-density housing(larger gardens &more spacious homes)
Describe the outer suburbs
An increase in densities of new build or social housing estates is common
Describe the Rural-urban fringe
Decline in densities. A very sharp decline maybe due to the presence of green belts
Describe the rural area in terms of population density
Lowest densities found in the remote rural areas
