Census Geography

Georgian delegation study visit at SE Tallinn, , 13.12 – 17.12.2010

Diana Makarenko-Piirsalu The Aims of Census Geography (I)

• To support the planning and taking census (other survey)

• Pilot census areas • Enumerator areas – each enumerator should know the territory to be enumerated • Supervisory areas • Visualisation the current state of the preparation

14 .12.2010 The Aims of Census Geography (II)

• To support the census dissemination

• Administrative units ( LAU – local Administrative units; NUTS - Nomenclature of Units for Territorial Statistics) • Functional territories (rural and urban areas = localities) • Grids

Census results should be easily used in many territorial levels

14 .12.2010 Census Geography territories , hierarchically sub-ordinated administrative territories postal areas voting districts previous enumeration areas …..

EA depends on the method of census and assigned work load of the enumerators

14.12.2010 Compilation of EA vs using Administritative areas or previous Census EA in Estonia

• New Census Method in use • Financial Pressure • Other Surveys = wishing all in one solution • Census 2000 EA are not applicable due to heavy changes is settlement patter changed work load

• Decision: compilation of new functional EA + areas for other surveys

14 .12.2010 Inhabitants in settlements does not correspond to the work load of enumerators

14 .12.2010 Pilot Census Areas , 2010

Census team needs info:

• Where the pilot census territories are located?

• How big are the territories?

• What is the current stage of the preparation?

14.12.2010 Enumerator Areas – represent workload for enumerator Rules applicable:

•Area must not consist of 2 separate areas

•Area must not contain “gaps”

• Area must not overlap

•Enumerator areas must be exhaustive (100% of the territory)

•The boundaries should be easily identifiable on the field

•Area must take into account the “natural barriers”

•Supports counting each person and housing unit once

14 .12.2010 Difficulties

• Difficult to estimate the % of e- census respondents in particular territory accurately • Change in work load after the pilot census is too late for GIS staff => rise the cost and decrease the quality

Compliaton of EA is time consuming Work load should not be changed after the beginning of compliation of EA

14 .12.2010 Dissemination Areas

• LAU - Local Administrative units • NUTS - Nomenclature of Units for Territorial Statistics) • Functional territories (rural and urban areas ( localities) • Grids

• Some other countries are using also: Enumerator areas Postal code disitricts Other territories ( agricultural zones, service areas etc….)

14 .12.2010 Localities  Main criteria

 Urban and rural population clusters  People live in the neigbourhood  Houses should not be apart more than 200 m

 Generetaing locality territorial units with the aid of GIS

 Using the standard GIS desktop SW (ArcEditor/ArcInfo)

14.12.2010 Independent statistics from the change of boarders

Benefits:

+ confidentiality

+ independent from the change of the boundaries of the administrative units

+ data are comparable in time and space; concistency in time and space

Buildings + comparability with goereferenced EnumeratorAgricultural areas Census results 1000m x 1000m grid parishes - 1992 parishes - 2008 Data need to be geo- referenced on the building or cadastral parcel level

14.12.2010 Census geographical territories are hierarichcal - Canadian example
