How to read the ACS data into SAS?

Greetings! How to read the data from Table DP05 of the 2019 American Community Survey (ACS) 5-year estimates into SAS? When I deleted the second row on variable definition and read it into SAS, errors came (copied below). When I read all lines starting the third row, all numbers became characters. I reviewed the user groups but could not find a good solution. 

I am new to ACS. I plan to run a multilevel analysis of 391 Latinx immigrants interviewed around 2019 to 2021 in Durham North Carolina. I want to generate a neighborhood concentrated disadvantage index using 2015–2019 5-year estimates of American Community Survey (ACS).

Thank you. Best wishes, Qing

  • I pre-edit the CSV file using a text editor.  I do a set of global search and replace operations.  For example, changing occurrences of ",**" to "," (change a comma-asterisk-asterisk to just a comma).  SAS will then treat these as missing values.

  • I don't think the INPUT statement works that way.

    You'll need to read in the whole record from DP05, then do your math

    INPUT
    GEO_ID $11
    NAME $60.
    DP05_0001E BEST12.
    DP05_0001M BEST12.
    DP05_0001PE BEST12.
    DP05_0001PM BEST12.
    DP05_0002E BEST12.
    DP05_0002M BEST12.
    DP05_0002PE BEST12.
    DP05_0002PM BEST12.
    [etc]
    ;
    Under18= DP05_0019PE / 100;
    Black = DP05_0038PE / 100;
    Hispanic = DP05_0071PE / 100;
    geoid = SUBSTR(GEO_ID,10,11);
  • Hi Qing -

    I think the problem is that some of the rows contain text annotation so that they cannot be read with a numeric informat like BEST12.  Your approach could work (PROC IMPORT followed by a DATA step).  However, you will need to check to be sure the value is a number before doing the conversion from text to number.  One way to check is to use the verify function:

    if verify(DP05_0019PE,'0123456789. ') = 0 then
        Under18=input(DP05_0019PE, BEST12.)/100;
    if verify(DP05_0038PE,'0123456789. ') = 0 then
        Black=input(DP05_0038PE, BEST12.)/100;
    if verify(DP05_0071PE,'0123456789. ') = 0 then
        Hispanic=input(DP05_0071PE, BEST12.)/100;

    I hope this help!

  • My mistake, you're trying to use an INPUT function, not statement. @David's answer below should work.

  • Thank you David and Glenn. The verify function solved the problem. With your help, I programmed neighborhood measures of concentrated disadvantage and ethnic enclaves, which was a dichotomous variable with Latinx/Hispanic concentration at the 90th percentile or higher of the distribution at census tracts. Among 215 Latinx participants in 42 census tracts in a survey study in NC, 22 Latinx participants lived in ethnic enclaves in five census tracts with Latinx concentration (% of Hispanic) ≥ 29.2% in a multilevel analysis of intimate partner violence for a conference abstract due 8/31. I am very grateful to your expertise and help to me in this data users group. Best regards, Qing
