【正文】 in the selfrepresent, the urbanrural ratio in 抽選層 should be 5,200:4,800, . the ratio of neighborhood mittees to villagers39。 mittees is about 208:192. Challenge how to determine the distribution of samples between urban and rural areas in each PSUs Deducting the 2,000 urban households in selfrepresentative, the urbanrural ratio in selected category should be 5,200:4,800 We can calculate that the ratio of neighborhood mittees to villagers39。 mittees is about 208:192 According to the urbanrural ratio of 6:4, urban sampling size should be 7,200, and rural area should be 4,800. Sampling Design Our thoughts: ?Divide the districts and counties into several intervals according to the level of urbanization(the rate of nonagricultural population ). ?For a PSU with a higher level of urbanization, we should allocate more neighborhood mittees to that PSU . Sampling Design Allocation criteria Neighborhood mittee Villager’s mittee 95% and above 4 0 50%～ 95% 3 1 15%～ 50% 2 2 15% and below 1 3 Allocation Criteria of Second Units Sampling Design Construct second sampling frame Determine the number of neighborhood/villager’s mittees sampled in PSU Selects neighborhood / villager’s mittees with PPS Sample 25 households in each selected SSU, Sampling of Second Units ?Considering the nonresponce, enlarge the sample size same as selfrepresentative.
