A fictional weighted proportion is not an official rate or a precision estimate.

Inputs, method and sources

Supplied input	Value	Unit
Final design weight	2	weight
Recorded 0/1 indicator under that exact definition	1	0 or1
Stratum and primary sampling unit	Fictional sampling stratum / Laggala Pallegama cluster
Exact binary indicator and reference period	Fictional indicator: Bg 300 paddy on an irrigated plot in the stated reference season; 1 = meets definition, 0 = does not

Weighted proportion = sum(weight×indicator0/1)/sum(weight). Report the classification and eligible population; use design information for uncertainty.

Retain sampling frame, strata, clusters, nonresponse and calibration. The prototype does not invent complex-design variance, confidence intervals or small-area precision. These fictional binary observations demonstrate design weighting. Do not pool changed definitions, population frames or reference periods; no official rate or design variance is produced.

Other required records: Survey weights; crop; variety; irrigation mode; hectares; season; sampling frame.

Rattota — small-area reporting / Rattota	Variance method, strata and cluster reference: Not provided	Obtain the missing evidence listed below
Panvila — small-area reporting / Panvila	Variance method, strata and cluster reference: Not provided	Obtain the missing evidence listed below

What the selected record shows. The supplied estimate 78,700 and standard error 12,592 give a relative standard error of 16%. The supplied 20% review criterion is an example assumption. Confirm the survey design and variance method before choosing a reporting level.

Next step. Obtain the missing evidence listed below. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.

Information still needed

Variance method, strata and cluster reference: Not provided

The variance method and design evidence are required; the review bound is illustrative.

Inputs, method and sources

Supplied input	Value	Unit
Responding sample units	120	selected units
Design-weighted estimate	78,700	LKR/household/month
Design-based standard error	12,592	LKR/household/month
Example maximum relative standard error	20	%
Variance method, strata and cluster reference	Not provided

Relative standard error=100×design-based SE/abs(estimate), only for a nonzero estimate and an actually supplied design-based SE. Sample count alone does not determine geographic precision.

Retain sampling frame, strata, clusters, nonresponse and calibration. The prototype does not invent complex-design variance, confidence intervals or small-area precision. The estimate and standard error are fictional monthly household-income statistics. The 20% review criterion is illustrative; sample count alone does not supply a design-based standard error.

Other required records: Sample counts; design weights; variance; geography; approved precision criterion.

Validation required

Fictional default example · 2025.

Fictional case / area	Information still needed	Next check
District population-profile scenario / Sri Lanka statistical reporting frame	See the source references and case inputs	Check the matching source records before interpreting the change
Service-coverage table scenario / Sri Lanka statistical reporting frame	See the source references and case inputs	Check the matching source records before interpreting the change
Local planning-brief scenario / Sri Lanka statistical reporting frame	See the source references and case inputs	Check the matching source records before interpreting the change

What the selected record shows. District population-profile scenario uses Population series / version 1. A revision check is required.

Next step. Check the matching source records before interpreting the change. Prepare change comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.

A version difference requires a dependency check; no published table is replaced here.

Inputs, method and sources

Supplied input	Value	Unit
Statistical series and definition	Fictional annual population-estimate series
Superseded series version	Population series / version 1
Current replacement version	Population series / version 2
Dependent publication or table reference	District population-profile scenario

What the selected record shows. Observed variable: 1 0 or1.

An indicator is not comparable when population or labour definitions change.

Inputs, method and sources

Supplied input	Value	Unit
Final design weight	2	weight
Recorded 0/1 indicator under that exact definition	1	0 or1
Stratum and primary sampling unit	Fictional sampling stratum / Laggala Pallegama cluster
Exact binary indicator and reference period	Fictional indicator: Employed person under the same stated reference-week definition; 1 = meets definition, 0 = does not

Weighted proportion = sum(weight×indicator0/1)/sum(weight). Report the classification and eligible population; use design information for uncertainty.

Other required records: Employment status; age scope; survey weights; geography; reference period.

Local weights, population coverage, design variance and ratio-yield interpretation still need confirmation. Positive illustrative weights do not demonstrate every calibration design.

5. Documents and images

Your institution has its own document and image library. Use the same library for reports, photos and other evidence.

Open this screen for Department of Census and Statistics See the presentation example

Department of Census and Statistics Documents and images prototype screen — Department of Census and Statistics. Prototype screen. Select the image to enlarge it.

What you can try

Open Documents and images. Check the institution name.
Use All files, Documents or Images to find a file. Open its preview or download the original.
Use a sample file to try Add file. Private is the starting choice. Public needs a source, permission to share and review.
Use Access preview to try the institution reviewer and Public visitor views.

Files added in the prototype stay in this browser. Public sharing is an access preview. Existing public reference links already work online.

What your institution needs to confirm

Does a separate library for your institution meet your needs?Should new files start as Private for the permitted institution team?Should Public access require a review of the file and sharing permission?What documents and images will you store? Give the file types, usual sizes and need for earlier versions.Which job roles may add files, read Private files and approve Public files?Which files must stay Private? What permission, licence or expiry rule is needed for Public files?What else should change in this library?

6. Data structure management

Data structure keeps the existing source tree, records, charts and map. Manage structure adds a place to propose changes to definitions.

Open this screen for Department of Census and Statistics See the presentation example

Department of Census and Statistics Data structure management prototype screen — Department of Census and Statistics. Prototype screen. Select the image to enlarge it.

What you can try

Open Data structure and choose Manage structure.
Use Add base domain for a main information area. Add inside creates a subject area, a nested subject, an entity type or a field under the right parent.
Give the definition a clear name, code and meaning. Reuse an existing definition when the meaning is the same.
For a field, check the data type, unit, required value, limits and missing-value rule. Save a Draft, then try the separate reviewer view.

An entity type means a kind of thing or event, such as a reservoir or an inspection. Drafts stay in this browser. A demo approval does not change real definitions, data, chart links or sharing rights.

What your institution needs to confirm

Do the existing main topics and subject areas match your institution’s work?Should definition changes stay Draft until the responsible reviewer checks them?Is it right to reuse the same entity type or field when its meaning is the same?Which main topics, subject areas, entity types or fields should we add or change?Which units, choices, limits, decimal places and missing-value rules must each new field use?Which job roles may edit definitions and review them? Who owns each main information area?When a meaning, unit or calculation changes, what review and version history does your institution need?

7. Users and access

User management shows example profiles for each institution. People and Roles and access let you review the proposed account screens.

Open this screen for Department of Census and Statistics See the presentation example

Department of Census and Statistics Users and access prototype screen — Department of Census and Statistics. Prototype screen. Select the image to enlarge it.

What you can try

Open User management and choose the institution. The rows are examples, not a list of your staff.
Use View access to check a role. An administrator title alone does not give access to Private files.
Try Preview invitation or Preview access change. Check the role, start date, optional end date and reason.
Review the example permissions and tell us which job roles should receive each one.

These are interface previews only. They create no account, send no email and change no access. Use example details in the preview. Institution verification does not grant a real permission.

What your institution needs to confirm

Do the proposed role names and responsibilities match your institution?Should access be limited to the assigned institution and the agreed dates?Should reading Private files need a separate permission, even for an administrator?Which job roles should view data, add files, review Public requests, edit definitions and manage users?Who should approve new access, set an end date or remove access when someone changes duties?Which user fields, roles or access checks are missing? Give role names rather than passwords or private account details.

9. Anything else we should change?

Which decisions or services are missing?Which forms or fields should change? Give the existing form reference where possible.What should change in the entry, checking, expert, map or report steps?Are the English, Sinhala and Tamil words clear? Give the screen name, current word and your suggested wording.Who should join the next review and what should happen next?
