The secondneighborhood has 50 white households and 50 black households. The third neighborhoodhas 50 white households and 30 black neighborhoods. What is the dis-similarity index forthis city

Answer 1

Answer:

There is 30% dissimilarity.

Explanation:

Dissimilarity index is = 0.5 × ∑ | (a÷A) - (b÷B) |

Where ,

a= population of white in neighborhood

b= population of black in neighborhood

A= total population of whites

B= total population of blacks

Thus we can solve,

= 0.5 × { | (100÷200) - (20÷100) | + | (50÷200) - (50÷100) | + | (50÷200) - (30÷100) |}

= 0.3

Thus there is 30% dissimilarity.
