9
Receiving and Batching
  • 5 Coding Supervisors
  • To receive the questionnaires from logistics
    office on behalf
  • Census Data Processing Unit
  • To batch the census questionnaires in EA
    order in the store
  • for processing

10
Programming (a)
  • Main Application SOFTWARE
  • The Integrated Microcomputer System (IMPS)
    developed by US Bureau of the census is a
    system for entry, editing, tabulation and
    management of census and survey data.
  • MODULES
  • Data Dictionary (DATADICT)
  • Data Entry (CENTRY)
  • Data Edit And Imputation (CONCOR)
  • Publication Tabulation (CENTS)
  • Quick Tabulation (QUICKTAB)
  • Table Retrieval (IRS)
  • Variance Calculation (CENVAR)
  • Data Entry Control (CENTRACK)
  • Utilities
  • Quit

11
Programming (b)
  • IMPS
  • Design of data structures
  • Data Capture
  • Verification
  • Validation
  • Tabulation
  • Other SOFTWARE
  • SPSS WIN Version 12.0
  • MS ACCESS

12
Training
  • Coders
  • Verifiers
  • Data Entry Operators

13
Operations (a)
  • Coding

14
Operations (b)
  • Data Entry / Verification / Validation / Back up
    / Tabulations

Set up a Tabulation Plan
Run Tables with IMPS and SPSS
17
Creation of Census Databases
  • Population
  • Housing
  • Ownership
  • Agriculture
  • Deaths
  • DBMS
  • MS-Access

18
Dissemination of Census Information
  • CDs
  • Internet
  • Monographs

19
Challenges with Manual Entry
  • Duplication of EA codes and household numbers
  • The use of F2 key in IMPS to force values that
    are out of range.
  • Transposition errors were prominent
  • Incomplete entry of household records
  • Incomplete entry of modules
  • Data Verification was not effective.

20
Benefit of Manual Data Entry Approach
  • Build institutional capacity by the purchase of
    more microcomputers which can be used for other
    activities after the census.
  • Creates employment facility and training for more
    people.
  • Data can be easily identified and keyed.
  • Inconsistent data can be identify and resolved
    before keying.
  • Relatively less expensive
  • Data was processed within reasonable period of
    eight months.
