Overview  Cross-Sectional Matching  Transcription Routines (Raw Data into Statistics-Package-Format)  Exploring Data-Sets EPUNet 2005 Training Course

ECHP Overview - Data Sets Contents of the ECHP UDB  Personal File  Household File  Register File  Relational File Above: One file per wave  Country File  Link File

ECHP Overview - Data Sets Contents of the ECHP UDB Personal File  All person related information in the ECHP  Only adult respondents  Similar variable structure across countries  Similar variable structure across waves

ECHP Overview - Data Sets Contents of the ECHP UDB Household File  Unit of analysis: Household  General information that is applicable for all household members  Similar variable structure across countries  Similar variable structure across waves

ECHP Overview - Data Sets Contents of the ECHP UDB Register File  Unit of analysis: persons  General information  Regardless of age or participation  Similar variable structure across countries  Similar variable structure across waves

ECHP Overview - Data Sets Contents of the ECHP UDB Relational File  Unit of analysis: persons (caution: repeated observations of persons!)  Display of the relation-matrix of persons within a household  Kinship, parent-child relationships, sibblings, etc.  Similar variable structure across countries  Similar variable structure across waves

ECHP Overview - Data Sets Contents of the ECHP UDB Country File  Unit of analysis: country  Display of general country specific information (PPP, Exchange rates, Population)  Single file  One set of variables per wave

ECHP Overview - Data Sets Contents of the ECHP UDB Link File  “Heart” of the ECHP  Unit of analysis: persons  Regardless of age or participation  General information for cross-sectional and longitudinal matches  Household membership in a given wave  Sampling information  Weighting information  Single file

Cross-Sectional Matching Procedures Cross Sectional Matches  Person-level Matching  Household-level Matching  Relational Matching Central identifiers for all of the above:  country  pid/hid Base for all matches: ECHP Link File EPUNet 2005 Training Course

Cross-Sectional Matching Procedures Matching: Logical order  First: country variable (country)  Second: household identifier (HID)  Third: personal identifier (PID) Always use this logical order! ‘sort by country hid pid’ (hid may be left out if no household based information is included in the data generation) Base for all matches: ECHP Link File EPUNet 2005 Training Course

Cross-Sectional Matching Procedures Person-level matching I - Same Individual  country  pid Examples of matches  Matching information of one Person across files oUsing personal information from the Register File and the Personal File oAdding information from the Personal File to the Link File

Cross-Sectional Matching Procedures Person-level matching - Across Individuals Examples of matches  Matching information of a child to the mother - Unit of analysis: Mother; additional child related information  Matching information of a husband to his wife - Unit of analysis: Wife; additional information of the husbands income, e.g. Central information stored within the Relation-File

Cross-Sectional Matching Procedures Identifiers within Files: Unit of analysis Basic info / File structure Personal File (Register File) Country PID (HID) Person Level Information Country File Country General country specific info Link File Country HID[waveN] PID Linking across waves Relationship File Country PID (HID) Linking across individuals Household File Country HID Household Level Information

Lab Session Day 2 Transcription Routines Transformation from PDB to UDB Exploring Data Sets Cross-sectional matching procedures

Transcription Routines (Raw Data into Statistics-Package-Format) From PDB to UDB  ‘Raw’ ECHP data comes in comma separated ASCII format.  ‘Raw’ ECHP data comes without any labels!  Transcription Routines for SPSS In SPSS: open syntax file: EPUNet 2005 Training Course

Transcription Routines (Raw Data into Statistics-Package-Format) From PDB to UDB  ‘Raw’ ECHP ASCII format without  Transcription Routines for SPSS: In SPSS: open syntax file: ‘UDB_readin.SPS’ ‘UDB_label.SPS’ Adjust pathnames to fit your file structure Run EPUNet 2005 Training Course

Transcription Routines (Raw Data into Statistics-Package-Format) From PDB to UDB - Result:  ECHP UDB Files in SPSS’ *.sav - format  Link File (1 file ‘ulink’)  Personal File (‘pfile[n]’ wave 1 to 8)  Household File (‘hfile[n] wave 1 to 8)  Register File (‘rfile[n] wave 1 to 8)  Relationship File (‘relat[n] wave 1 to 8)  Country File (1 file ‘ctryvars’) EPUNet 2005 Training Course

Exploring Data Sets - See Doc-Pan 166 Personal File  Open Pfile Get file = ‘X:\path1\a_w8p.sav’. Descriptives variables PE001. For self defined employment status  Continue with ‘a_w7p.sav’, ‘a_w8h.sav’, ‘ulink.sav’, etc. EPUNet 2005 Training Course

Exploring Data Sets Personal File - contents  Demographic information  Employment and activity  Calendar of activities  Income  Educational attainment  Current education and training  Health/Care  Migration  Satisfaction EPUNet 2005 Training Course

Exploring Data Sets Household File - contents  Demographic information  Household income  Household related benefits  Accommodation and housing situation  Durables  Persons in household. EPUNet 2005 Training Course

Exploring Data Sets Register File - contents  Panel specific information (personal identifier [PID], household identifier, weights, etc.  Demographic information (age, sex, etc.) EPUNet 2005 Training Course

Exploring Data Sets Relationship File - contents  Always lists two persons per case!  Central: relation between person one and person two (pid1 relation pid2) EPUNet 2005 Training Course

Exploring Data Sets Country File - contents  One record for each country/panel  One block of variables for each wave  RATE: Exchange rates in Euro  PPP: Purchasing power parities  POPTOT: Total population in private  households  POP16P: Number of persons aged 16+ living  in private households  POPHHD: Number of private households EPUNet 2005 Training Course

Exploring Data Sets Link File - contents  General structural information for linking households and individuals within and across waves  All panel household members (regardless of age or panel participation)  Basic demographic information  Cross sectional and longitudinal weights  Sample status  Wave specific household identifiers EPUNet 2005 Training Course

Exploring Data Sets General structure:  Identical naming of variables across waves  First letter of variable describes file (‘P’ for Personal File)  Second letter of variable describes module (‘PM for Personal File, module migration)  Subsequent numbers describe exact information (PM001 for Personal File, module migration 001 for migration trajectory) EPUNet 2005 Training Course

Exploring Data Sets Getting information: Central tool: Codebook (Doc-Pan 166) containing:  List and description of all ECHP UDB variables and information on availability and comparability of variables  across countries and  across waves EPUNet 2005 Training Course

Files to use  Personal File  Household File  Register File  Relationship File  Country File  Link File  UDB_readin.sps  UDB_label.sps
