Question

Which of the states in the table has the least population density

Answer 1

`UTAH:38.53\:(inhab)/(mi²)`

1) Demographic densities are found by writing one simple ratio:

`\begin{gathered} D=(pop)/(area) \\ \end{gathered}`

2) So, let's find the demographic density of each state and then compare them:

`\begin{gathered} d_(UTAH)=(3271616)/(84896.88)=38.53(inhab)/(mi²) \\ d_(OKLAHOMA)=(3959353)/(69898.87)=56.64 \\ d_(ILLINOIS)=(12812508)/(57913.55)=221.23 \\ d_{WEST\text{ VIRG}}=(1793716)/(24230.04)=74.02 \end{gathered}`

The least dense state, therefore, is Utah.
