2004 PUMS Top Coded Values

The following eleven housing variables and nine person variables are topcoded in the Public Use Microdata Sample files:

The tables below show the topcode values for each of these variable by states. These topcodes were derived based on the following rules:

1. Within each state, all base dollar amounts are topcoded using the mean of all cases greater than the topcode national minimum value.
2. The maximum bottom-coding value for all component income dollar amounts which can be negative is $10,000.
3. Recodes of dollar amounts use the rounded top-coded or bottom-coded base dollar amounts without any additional top-coding or bottom-coding.
4. Top-coded Property taxes are further assigned to one of 68 categories.
5. AGE is top-coded using the state mean of all cases greater than 90.
