By the trend that is being given above, the population of New Jersey will only be 99.88% of the population from the previous year. It may be calculated through the following equation,
                               P(n) = P(0) x (1 - r)^n
Substituting the values from the given above,
                                  P(n) = 79,318 x (0.9988)^(2015 - 2006)
                                          = 78465.47
Thus, the population will approximately be 78,466.
