Census Base Rent Calculation for
Scott County, IL

The 2000 Census Base Rent for Scott County, IL used by HUD is $433.

This rent is the 40th percentile recent mover rent for the county group defined below because the recent mover sample size for Scott County, IL is too small.

FMR Area Geography

Scott County, IL has an insufficient 2000 Census sample of recent movers to compute its own recent mover rent. The number of units in the standard quality sample is also too small to compute a standard quality rent for Scott County, IL alone. HUD requires a sample of at least 200 recent movers, but Scott County, IL has fewer than 200 units in the protected data sample. Therefore, Scott County, IL is assigned the recent mover rent for the combination of counties listed below, even though some members of the group may have a sufficient sample size for their own FMR or may be parts of metropolitan areas. Other FMR areas that use the same county group recent mover data are indicated by "*". Other FMR areas that use the same county group standard quality sample data are indicated by "#".

Members of the county group: Calhoun County, IL*; Cass County, IL; Greene County, IL*; Macoupin County, IL; Morgan County, IL; Scott County, IL*#.

User Note

In computing 2000 Census Base Rents, HUD actually uses data on rent distributions that are prohibited from public release under Title XIII to protect the confidentiality of respondents. The distributions used in this demonstration are rounded versions of the actual, protected data.

The rounding scheme is as follows:

0, count = 0
1 to 7, count = 4
all other counts are rounded to the nearest 5 (e.g., 10, 15, 20, 25, etc.)

CALCULATIONS USING THE ROUNDED DATA MAY NOT PRODUCE THE SAME RESULT AS CALCULATIONS USING THE PROTECTED DATA. THE DIFFERENCE BETWEEN HUD'S ACTUAL RESULTS AND THOSE DEMONSTRATED HERE IS INVERSELY RELATED TO THE SIZE OF THE FMR AREA. THAT IS, THE LARGER THE AREA, THE CLOSER THE CALCULATION BASED ON THE ROUNDED DATA IS LIKELY TO BE TO THE CENSUS BASE RENT COMPUTED FROM THE PROTECTED DATA.

Recent Mover and Standard Quality Rents

HUD uses rents for recent movers in standard quality units to set the 2000 Census Base Rent. "Standard Quality" units and rents are determined by limiting the full Census sample by including only responses meeting the following criteria:

a. Occupied rental units paying cash rent
b. Specified renter ? on 10 acres or less
c. with full plumbing
d. with full kitchen
e. built before 1999
f. meals not included in rent

"Recent Mover" rents are determined by further limiting the "Standard Quality" sample with the following additional criterion:

g. moved in within the last two years

The 2000 Census did not include a question that could be used to filter public or assisted housing from the rental distributions, however HUD is required to ensure that FMRs exclude non-market rental housing in their computation. Therefore, HUD excludes all units falling below a specified rent level determined from public housing rents in HUD's program databases as likely to be either assisted housing or otherwise at a below-market rent (perhaps due to quality problems not otherwise captured by the Census questions). The "public housing" rent cut-off in Scott County, IL is .
