As an aside, for single-victim crime incidents, what is recorded in variables V4007 to V4016 will be the same as what is recorded on the NIBRS offense records. Variables V4007 to V4016 record the offenses that the victim experienced. However, to be complete we need to look at all possible offense variables. The vast majority of victims experience one offense. NIBRS records up to 10 offenses per victim. There is no one total population variable in NIBRS. However, there are a few hundred that have populations in multiple counties. The vast majority of cities have all of their population in one county. The five CURRENT POPULATION variables record the portion of the city population that is in each county. NIBRS recognizes that some cities may span more than one county. Variables BH019, BH023, BH027, BH031, and BH035 are five population variables. It will also be useful to verify that we merged this data with the LEAIC data correctly. ORI is necessary because it is what we will use to link to the LEAIC.īH007 - CITY NAME, while technically not necessary, is a useful descriptive variable. Referring to the codebook helps identify what variables are needed. We do not need all the information included in it, so we'll just keep the variables we need. Once converted to SPSS, the file is approximately 5.5 GB. Note: For a more detailed guide to using SPSS Setup files to read text data files, see this ICPSR guide Select NIBRS Variables In File, click Save As and name the file da36121-0002.sav. Save it as an SPSS file for use throughout this guide. When the bottom of the SPSS window says "IBM SPSS Statistics Processor is Ready," it's done running. Reading the file into SPSS may take several minutes. Once you have made these changes, click Run -> All. We need to change this to the real name of the file, 36121-0002-Data.txt.įILE HANDLE DATA / NAME="data-filename" LRECL=1003.įILE HANDLE DATA / NAME="36121-0002-Data.txt" LRECL=1003. Right now, that file is called "data-filename". The value in the quotation marks in line 50 tells SPSS the name of the file you want it to read. Make sure that both the data file and the Setup file are inside the working directory folder. You must copy the above line (after changing the part inside the quotation marks to your own working directory) into the Setup file BEFORE line 50. * cd 'Users/ICPSR/Desktop/Research/LEAIC'. * a Windows machine, an example of a path structure on a * Note that the above example is that path structure for * cd 'C:\Documents and Settings\Research\LEAIC'. * An example working directory command would be Throughout this guide, we act as if the files are within the Working Directory. A good practice is to keep all of your needed files in a single folder and set that folder as the Working Directory. The working directory tells SPSS to look in a specified folder for each file that you mention. The first is to set your working directory. There are two changes you need to make to this file.
#SPSS CODE EXAMPLE HOW TO#
This opens up an SPSS Setup file, which is an instruction manual to SPSS for how to read the data file. Choose the file 36121-0002-Setup.sps and click Open. Open SPSS and in the file menu, click File -> Open -> Syntax. We will then save it as an SPSS file for use throughout this guide. You will need to use the Setup file to read the data file into SPSS. Note: In this walkthrough, we will provide SPSS syntax on a step-by-step basis. Within that, the key folder is "DS0002" which contains the setup file ( 36121-0002-Setup.sps) and the data file ( 36121-0002-Data.txt). Within ICPSR_36121-V2.zip there is a folder called ICPSR_36121. ICPSR has a guide on how to handle zipped files.
#SPSS CODE EXAMPLE SOFTWARE#
Because the file is zipped, you may need software designed to open compressed, or zipped, files.
#SPSS CODE EXAMPLE ZIP FILE#
Clicking ASCII + SPSS Setup will download a zip file called ICPSR_36121-V2.zip which has a number of folders and files inside it. Since we are going to load this file into SPSS using an SPSS Setup file, click ASCII + SPSS Setup in the DS2: Victim-Level File download area. On this study’s homepage, there are a number of datasets available to download within the Data & Documentation tab. The NIBRS file is ICPSR study #36121, and we want the DS2 Victim-Level File (data set number 2 - Victim-Level Extract File).

#SPSS CODE EXAMPLE ARCHIVE#
This file is located on the National Archive of Criminal Justice Data website, meaning that you will need an account to be able to download this data. We will use the NIBRS Extract Files for 2013. Example Task: Calculating Homicide Victimization Rates
