In response, we have archived the predecessors (NUTS 2010; 1995, 2002 or 2005 to 2014) by marking the description metadata as "discontinued." The replacements (NUTS 2013, see related article) start at 1995 or 2002. Figures are unitary count (#). Although this particular change pertains only to NUTS 3 areas in the dataset, geo coverage is the nation and all NUTS 2013 level 1, 2 and 3 areas.

Additionally, existing series have been changed in magnitude by the source from thousands unitary count (Ths. #) to unitary count (#) across all geo levels (see related article).

The new and discontinued series reside in the historical catalog (Poland » Demographics » Population » Annual by age) and include, for example:

• VSQPOPTUA.IPOL_OST    = [DISCONTINUED] Population - All ages, (Ths. #) - for NUTS (2010) 3 Ostrolecko-Siedlecki
• VSQPOP5054UA.IPOL_SWE = Population - Ages 50 to 54, (#) - for NUTS (2013) 3 Swiecki
• VSQPOPTUA.IPOL_MZ     = Population - All ages, (#) - for NUTS 2 Mazowieckie

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