Question

the table shows how several different populations have changed over a one - year time span. look at each population and determine which population has had an overall increase?

populatio n	births	deaths	# of individuals that emigrated	# of individuals that immigrated
b	20	1	50	1
c	50	1	1	50
d	100	200	0	0

population c
population a
population d

Explanation:

Step1: Calculate change for Population A

Net change = Births - Deaths - Emigrated+Immigrated = 10 - 10 - 50+0=-50

Step2: Calculate change for Population B

Net change = 20 - 1 - 50 + 1=-30

Step3: Calculate change for Population C

Net change = 50 - 1 - 1+50 = 98

Step4: Calculate change for Population D

Net change = 100 - 200 - 0+0=-100

Answer:

Population C
