Central Demographics File (MSP Registration and Premium Billings, Client Roster and Census Geodata)/Consolidation file (MSP registration and premium billing) data set

Data sources: 

  • BC Ministry of Health Services
  • BC Ministry of Health Services Registration & Premium Billing (R&PB) files
  • BC's health services utilization files -- Medical Services Plan (MSP) Payment Information, Discharge Abstract Database (Hospital Separations)
  • BC Stats Translation Master File (TMF)
  • Statistics Canada Postal Code Conversion File (PCCF)

Description

The Central Demographics File (also known as the Consolidation File) is Population Data BC's central demographics file for research requests. Requests for access to demographic information should, in most cases, refer to this file rather than to individual content data files.

The Consolidation File contains basic demographics such as age and sex, geo-codes indicating location of residence, and registration data. The primary base of information are the MSP Registration and Premium Billing (R&PB) files, but other data sources are also used to augment this base, e.g. to identify individuals who appear not to be registered but still receive health care services.

 

Variables available

Both Core and Non-Core variables are available for this data set.

Core vs. Non-Core Data

  • Core Data: Some BC Ministry of Health data sets available through PopData and HDPBC are called ‘Core Data’. A Core Data set is a standardized ‘bundle’ of commonly requested variables. A Core Data set may not include ALL the variables available in the data set. For example, some Core Data variables, such as geography or organisational codes, are suppressed to meet privacy legislation requirements.
  • Non-Core Data: Non-Core Data are variables that are NOT included in the standardized Core Data set. Non-Core Data is available for request as an addition to the Core Data set.

For the majority of DARs, requesting access to Core Data ONLY may make the data access approval process quicker and may expedite data provision. Data requests that include Non-Core Data will be subject to regular rather than expedited processes, both for application review and data provisioning.

Please note that the overall data access request is subject to meeting ALL of the Five SAFEs requirements. For more detail on the Five SAFEs, visit the Eligibility and the Five SAFES model page of our website.

Data update schedule

Client Roster snapshots (fiscal and calendar) are generally updated annually in the fall by the BC Ministry of Health. PopData updates its data collection quarterly. 

Please note: Our data update schedule depends on when the data is made available to us by the data provider, so the update schedule is an estimation only. 

Inclusions
  • All individuals who are registered as being eligible to receive services in BC, and/or who actually do receive services are represented in the Consolidation File.
Data changes over time
  • Ongoing updates to the data based on new census information
  • Changes to the geographic fields available
  • Changes in how the Socioeconomic (SES) quintiles/deciles are calculated (see additional details below).
Quality/accuracy of information/field coding source
  • Programmers at Population Data BC check for consistency in demographic information over time. Where there are inconsistencies in birth date or sex, for example, care is taken to identify the most likely or best available information and to use that consistently for that individual across years. For example, an individual may be coded with "sex unknown" in one year, but on inspection be found to be coded consistently as "female" in other years. In this case, the "unknown" is modified to "female" in the Consolidation File.
  • Unlike the source MSP R&PB files, which may contain multiple records per person per year, the Consolidation File contains a single record per person within either a calendar year or a fiscal year.
  • The Consolidation File contains two summary registration fields developed by Population Data BC, which should be easier for researchers to use in their analysis: ‘Registration Start Day' (point in the year that their registration started) and ‘Total Days Registered During the Year'. These fields were developed by Population Data BC based on the sometimes multiple and overlapping enrollment and cancellation dates which appear in the MSP R&PB files.
  • We use the PCCF+ software packages developed by Russell Wilkins of Statistics Canada to automatically assign a full range of Census geographic areas (e.g. Census Division, Census Subdivision, Census Metropolitan Area, Census Tract, Dissemination Area, etc.) as well as neighbourhood income quintiles/deciles to BC patients based on postal code of patient residence. The software assigns postal codes probabilistically based on population weights for rural postal codes and some urban postal codes. Each version of the PCCF+ software is designed for use with data from a particular Census (completed once every 5 years). At this time we do not have the applicable PCCF+ software versions to use on data prior to 1994, thus we are unable to assign Census geographic identifiers and neighbourhood income quintiles/deciles to data prior to 1994.
Important additional information
  • There are several special populations that one must be aware of when conducting research using administrative data:
    • First Nations
    • Federal employees (e.g. RCMP or Armed Forces)
  • The way coverage for these groups is managed creates some peculiarities for data in the source MSP R&PB files and thus in the Consolidation Files. In these cases, federal coverage of health care services is limited to the individual or employee, i.e. does not extend to any of their dependents. In cases where the RCMP or Armed Forces personnel have dependents, the federal employee is issued coverage, and they are assigned a PHN, but that number is not communicated to the federal employee. Their coverage is both issued and cancelled on the same day to facilitate the creation of a dependent number for the ‘economic family.'
