ethiopia census 2007

1)What is DRS experience in Census?

Ethiopia census 2007:
  • 23 million forms
  • 11 DRS scanners in total.
  • Keying of corrections from image
  • Data capture Contract, funded by UNDP
3 which scanning technology should be selected
3) Which Scanning Technology should be selected?
  • OMR
  • ICR
  • or OMR/ICR/Keying combination
  • Use a scanning solution which is appropriate for you
3 which scanning technology should be selected1
3) Which Scanning Technology should be selected?
  • Scanners with a heavy duty metal construction, 24 hour duty cycle
  • Open paper path – with an ability to detect and prevent double feeds
3 which scanning technology should be selected2
3) Which Scanning Technology should be selected?
  • Easy to replace consumables
  • Scanners designed for African climate and geography
  • Scanners which can be operated and maintained by your staff

DRSPS900:

a Desktop scanner

slide13

4) On what basis should

a data capture supplier be chosen?

  • Select supplier offering:
  • Combined solution of forms and scanners for census
  • Track record in International census
slide14

5)How should Forms be designed?

  • Design your form in collaboration with technology provider

Census forms need to be designed precisely and with enumerator task in mind

  • Finalise the form design in good time in advance of census
slide16

6)Printing forms?

  • Print forms with sequential unique barcode
  • Print with ISO 9001:2000
  • Print on suitable paper and use correct inks
slide17

7) What speed benefits can

be expected by using scanning?

scenario

7) What speed benefits can

be expected by using scanning?

Scenario

1 million formsData to be captured in one month

slide19

7) What speed benefits can

be expected by using scanning?

1 million forms

  • Keying OMR
  • 7,200 keystrokes/ hr 3,000 forms /hr
  • 360 forms 8 hour day 24,000 forms day
  • 1,800 forms per week 120,000 forms/week
  • 7,200 forms per month 480,000 forms/month
  • 139 operators 3 PS900s
slide21

Tanzania Census

  • Nov 2001 :
  • 100K pilot, end to end, using DRS forms, scanners and software
slide22

Tanzania Census

  • Aug 2002 – Census period
    • 35K enumerators,18M DRS OMR census forms:3.5M long and 14.5M short
slide23

Tanzania Census

  • Sept 2002 start scanning
  • Early 2003: Announcement of preliminary results
slide24

8)What purpose has the Pilot Census?

An opportunity to experience the technology trial your systems, test your training, staff and data capture infrastructure

Implement necessary changes for main census

10 filling in of forms
10)filling in of forms
  • Fill in the forms

correctly!

slide31

10)filling in of forms

  • Training of enumerators is fundamental to success!
  • Use the correct pencils, shade the responses properly, keep the forms dry
  • Treat the forms with respect!
slide32

10)filling in of forms

  • Bonus on successful scanning of their forms?
  • Awards for excellence in service?
slide33

10)filling in of forms

  • Emphasise team work – give enumerators a uniform/distinct census identity? – make them proud to be selected.
  • Training & motivation of enumerators is fundamental to success!
11 prepare the forms for scanning
11) Prepare the forms for scanning
  • quality control starts before scanning
slide37

12) Keep Track of the forms

As they go through the data capture process

  • Control software in place to manage:
  • distribution of forms,
  • receipt of forms at the scanning centre
  • batch processing at the scanning centre
slide39

13) scanning of the forms:

  • Have a suitable computer network and infrastructure in place and scanning workflow/ environment
slide41

14)if forms not filled in correctly?

  • Validation/logic rules to be agreed in advance
  • Management to control the correction process – clear lines of authority on what corrections can be made, by whom and under what circumstances
  • Correction on screen
slide45

Summary 1)

  • Note of Caution:

Modern Scanning techniques are not a “Panacea” to solve all census problems

  • Modern Scanning techniques are a tool to be used
slide46

Summary 2)

  • Select supplier offering:
  • Combined solution of forms and scanners for census
  • Track record in International census
  • A long term commitment and record in major data capture projects in Africa
  • Track record with donor agencies
  • A cost effective and appropriate solution
slide47

Solutions for census data capture:

High Speed,

Accurate, Cost Effective
