Between sub tropical and temperate latitudes ➡️ comfortable climate
Along edges of continents ➡️ close to coastline
In lower lying areas ➡️ access to water
Less then 200m above sea level ➡️ warmer and closer to coast
Physical factors of density (6)
Accessibility ➡️ eg coast easy to reach
Relief ➡️ low lying preferred over mountainous
Soil fertility ➡️ more food produce, better quality
Climate ➡️ attracted to moderate climates
Natural vegetation ➡️ shortage leads to over grazing

What is life expectancy
Number of years that the average person may expect to live
