The Social Statistics Database:


Contents of this pesentation

Contents of this pesentation

  • What does the Social Statistics Database (SSD) contain?

  • Linkage keys

  • Standardization

  • Data and metadata

  • Process

  • Privacy-protection

  • Output-examples


Ssd contents

SSD: contents

The SSD is a central database containing microdata on:

  • Persons

  • Relations between persons

  • Households

  • Jobs

  • Self-eployment

  • Social security benefits

  • State and employer pensions

  • Income

  • Education

  • Hospitalizations

  • Causes of death

  • Criminal offense reports

  • Houses

  • Vehicles

and more……


The social statistics database

Many administrative sources, such as:

  • Population Register

  • Register Income Tax Declarations

  • Administration of Employee Insurance Schemes

  • Police Register

  • Valuation of real estate registration system

    Survey:

  • Labour Force Survey

    Future developments: more administrative sources, more surveys, big data?


Ssd linkage keys

SSD: linkage keys

All mirco datafiles stored in the SSD contain a LINKAGE KEY:

Interlinking microdata is what the SSD is about!

Example:

linking microdata on graduates with data on persons and data

on employment in order to describe the transisiton from

education to labour market participation


The social statistics database

SSD: contents and linkage keys

PIN: person identification number

HIN: household identification number

AIN: adress identification number

EIN: enterprise identification number


Ssd standardization

SSD: standardization

standardization is an important aspect of the SSD

  • organization of the IT-infrastructure

  • file formats

  • linkage keys

  • names

  • metadata


Ssd relation between data and meta data

SSD: relation between data and meta-data


The social statistics database

In conclusion:

Microdata-files are linked to other microdata-files by means of a set of standardized linkage keys

Microdata-files are linked to their metadata through the name (file-name / variable-names)


Ssd process

SSD: process


Ssd privacy protection

SSD: privacy-protection

Legislation:

  • Statistics Netherlands Act

  • Netherlands Data Protection Act

    These laws:

  • authorize Statistics Netherlands to use personal data

  • oblige Statistics Netherlands to take adequate measures aimed at privacy protection


The social statistics database

Privacy protection measures:

  • Linkage keys are anonymous, original personal identifiers are removed from the data

  • Access rights to the SSD are restricted

  • Limited e-mail facilities

  • Staff members have to take an oath

  • Check on disclosure risk of output


Ssd examples of output

SSD: Examples of output
