MICS4 Data Processing Workshop

Exporting ‘clean data’ from CSPRO to SPSS – By using CSPRO dictionary and final data file, we create ASCII rectangular data files (*.dat) and corresponding syntax files (*.sps) to read the data into SPSS – All located in ‘c:\mics4\spss’ directory • c:\mics4\spss\myhh.sps • c:\mics4\spss\myhh.dat •…

Rectangular data files [*.dat] • • • • •

myhh.dat - [Household] myhl.dat – [Household members] mywm.dat – [Women] mych.dat – [Children] mytn.dat – [Mosquito nets] – Only if ‘ITN’ module’ is included • myfg.dat – [FGM] – Only if ‘FGM’ module’ is included • mybh.dat – [Births to women 15-49] – Only if ‘Birth History’ module is included • mymn.dat – [Men] – Only if ‘Men’ questionnaire is included MICS4 Data Processing Workshop

Rectangular data files [*.dat] – HOUSEHOLD QUESTIONNAIRE • myhh.dat - [Household] • myhl.dat – [Household Members] • mytn.dat – [Mosquito nets] – INDIVIDUAL WOMEN QUESTIONNAIRE • mywm.dat – [Women age 15-49] • myfg.dat – [Female genital cutting. women age 15-49] • mybh.dat – [Births to interview. women age 15-49] – UNDER-5 QUESTIONNAIRE • mych.dat – [Children] – INDIVIDUAL MEN QUESTIONNAIRE • mymn.dat – [Men age 15-59] MICS4 Data Processing Workshop

Rectangular data files [*.dat] • Rows are ‘cases’ – – – – –

Household – all (interviewed or not) Members - living in interviewed households Women – all (interviewed or not) Children – all (interviewed or not) Nets – mosquito nets in interviewed household • Only if ‘ITN’ module’ is included – Daughters – daughters under 15 years of age of interviewed women age 15-49 • Only if ‘FGM’ module’ is included – Births – births to interviewed women age 15-49 • Only if ‘Birth History’ module is included – Men – all (interviewed or not) • Only if ‘Men’ questionnaire is included

• Columns are ‘variables’ – Cluster, Household number, Line number, Interviewer number, etc.

Syntax files (to read rectangular data files) • • • • •

myhh.sps myhl.sps mywm.sps mych.sps mytn.sps – Only if ‘ITN’ module is included • myfg.sps – Only if ‘FGM’ module is included • mybh.sps – Only if ‘Birth History’ module is included • mymn.sps – Only if ‘Men’ questionnaire is included •

Includes the location information (columns) of variables in rectangular data file as well as variable labels and value labels

Screenshot • Sample Syntax file

Importing Data to SPSS – Executing syntax files created by CSPRO – In SPSS, run all my*.sps files (one by one) • The my*.sps files will import the data into SPSS and create SPSS-format data files (system files *.sav), with variable labels, value labels etc.

– At the end of each run, save your work in data files as hh.sav, hl.sav, wm.sav, ch.sav [tn.sav, fg.sav, bh.sav, mn.sav] MICS4 Data Processing Workshop

Saving the Data File • It is helpful to have the syntax file automatically save the data file that it creates • To do so, add the following line to the end of the syntax file: save outfile = 'hh.sav'.

Run frequency distributions • Open SPSS and run frequency distributions for all of the variables in all 7 files • Detect any unexpected codes or inconsistencies, and if necessary, return to CSPro and make corrections.

Next Steps • Recoding variables – Creating new variables by recoding existing variables – Adding variables to different levels • Mother’s education • Father’s education

MICS4 Data Processing Workshop

Customize make*.sps • Customize the make*.sps syntax files, in accordance with the contents of your questionnaires • Take out any variables and associated syntax which are not included in your questionnaire, or modify the variables according to your response categories

Run make.sps • Run make.sps to recode all additional variables needed for the tabulations • make.sps is provided as a batch file which calls and runs each of the make*.sps files in turn

• All *.sav variables will be replaced! • Backup before you proceed to this stage

Next Steps • Adding sample weights – Sample weights are added from weights spreadsheet

MICS4 Data Processing Workshop

Calculate weights • Obtain distribution of interview results by the unit based on which you intend to calculate unique sample weights: - using the weights_table.sps syntax file, if calculation at cluster level - using the weights_table_alt.sps syntax file, if calculation at stratum level, e.g. regions and area

Calculate weights cont. • Calculate final sample weights • using weights.xls, if calculations are carried out at the cluster level • weights_alt.xls, if calculations are carried out at stratum level

Calculate weights cont. • Once calculations in weights.xls or weights_alt.xls have been completed, save the “Output” workbook – c:\mics4\weights\weights.xls

Append sample weights • Append sample weights to the exported SPSS files hh.sav, hl.sav, wm.sav, ch.sav (tn.sav, fg.sav, bh.sav and mm.sav if relevant modules included), by using the SPSS weights_merge.sps or weights_merge_alt.sps syntax file – Need customization if ITN, Birth History modules or Men questionnaire included

Next Steps • Adding wealth index – Wealth index calculated then added to files

MICS4 Data Processing Workshop

Customize wealth.sps • Customize the wealth.sps syntax file that calculates wealth index values, together with the survey coordinator/technical manager, according to the items included in your questionnaire

Run and append wealth • Run the customized SPSS syntax wealth.sps to calculate and append wealth index values to all of the exported data files

Next Steps • Adding GPS data – Geographic location data added to files

MICS4 Data Processing Workshop

Next Steps • Tabulation – Tables are generated from the *.sav files

MICS4 Data Processing Workshop

Customize each syntax • Customize all tabulation syntax files in accordance with the contents of your survey • Delete the syntax files which are used to obtain tables on topics which are not included in your survey

Run all_tables.sps • Once all tabulation syntax files are customized and free of errors, customize all_tables.sps • all_tables.sps calls and runs all tabulation syntax files, and produces an output which includes all tables • If any of the tabulation syntax files have errors, the program will stop and you will have to correct the tabulation syntax file. Then re-run all_tables.sps
