Incidence is the number of new cases of a disorder in a specific period of time in a given population. In this case, there were 50 new cases out of a total of 1,000 people. To calculate the incidence, we can use the formula:
Incidence = (Number of new cases / Total population) x 100
Plugging in the values, we get:
Incidence = (50 / 1,000) x 100 = 5%
Therefore, the incidence of the disorder is 5%. Choice B is the correct answer.
