Data Change: Taiwan subnational - Population by age - Overhaul
Tuesday, 27 Aug 2019 10:09 ET
By Ian Vaughan
August 2019 -- For population by age for Taiwan and subnational areas thereof, we have overhauled our extract (127 new annual series from 1974, 651 annual series revised from 1974).

We have overhauled the dataset:

  1. Standardized mnemonics.
  2. Added series for previously overlooked age brackets and geos.
  3. Discontinued two age brackets that were terminated by the source:
    • Ages 85 and older
    • Ages 90 and older
  4. Discontinued seven geos that were terminated in administrative reforms.

Dataset properties:

  • Measurements: Unitary count of persons (#)
  • Seasonal adjustment: Not applicable
  • Measurement point: End of year
  • Native frequency: Annual
  • Geo coverage:
    • Active: Taiwan, five large cities, 19 counties or small cities
    • Discontinued (1991 to 2010): Kaohsiung Municipality and County, Taichung City and County, Tainan City and County, Taipei County (ITWN_KAOC and ITWN_KA, ITWN_TC and ITWN_TA, ITWN_TN and ITWN_TI, ITWN_TP)
    • Discontinued (1991 to 2000): Taiwan Area, Taiwan Province (ITWN_TAIA, ITWN_TAPR)
  • Date ranges: 
    • Active: 1991, 2001 or 2011
    • Discontinued: 1991 or 1992 to 2010
    • Discontinued (85- and 90-year brackets only): 1974 or 1975

The series reside in the historical catalog (Taiwan » Demographics » Population » By age) and include, for example: 

  • VSQPOPT85GUA.ITWN       = [DISCONTINUED] Vital statistics: Population - Both sexes - Ages 80 to 84, (#)
  • VSQPOPTUA.ITWN          = All ages, (#)
  • VSQPOPT6569UA.ITWN_KAOC = [DISCONTINUED] Ages 65 to 69, (#) - for Kaohsiung Municipality
  • VSQPOPT3034UA.ITWN_CA   = Ages 30 to 34, (#) - for Changhua County

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.

Please be aware that

As of 2011, an administrative reform merged three pairs of areas (large city and surrounding county) and promoted one city. To describe this redefinition, we declared separate geo codes.

  • Kaohsiung: ITWN_KA and ITWN_KAOC merge to ITWN_KAOH
  • Taichung: ITWN_TA and ITWN_TC merge to ITWN_TAIH
  • Tainan: ITWN_TI and ITWN_TN merge to ITWN_TAIN
  • Taipei County ITWN_TP promoted to New Taipei City ITWN_TAIP

Despite the similar names, Taipei City and New Taipei City are physically and administratively distinct areas.

The term "subnational" in this context denotes "areas contained within the area designated by a country-type geo code". For statistical convenience, Data Buffet assigns country-type geo codes to Hong Kong SAR, Macau SAR, and Taiwan ROC. Moody's Analytics takes no position on the dispute between the People's Republic of China and Taiwan (Republic of China) regarding sovereignty of the latter.
