In response, we have marked the series as "discontinued" in their metadata. All other geographies are unaffected. The series run from as early as 1995 to as late as 2007.

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

• VSQPOPTNTUA.IDEU_14167    = [DISCONTINUED] Population: German nationals - Total, (#, NSA) - for Zwickau, Kreisfreie Stadt
• VSQPOPT39UA.IDEU_14374    = [DISCONTINUED] Population: Total - 39 years, (#, NSA) - for Delitzsch
• VSQPOPFN0003UA.IDEU_15202 = [DISCONTINUED] Population: German nationals - Female - 0 years to 3 years, (#, NSA) - for Halle/Saale, Stadtkreis

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