I have added the "transport" section from the German article. What I can offer from that article:
Population since 1850
Statistics as to the number of foreigners (in 2007: 27%), people by religious creed (43% Reformed Protestant, 34% Roman Catholic, 8% Muslim, 2% Eastern Orthodox, 1% others; numbers rounded to the closest percent), by main language: 78% German, 9% Italian, 2% each Turkish, Albanian, Serbocroat, or Portugese, 1% each Spanish, French or English)
Lenzburg is a mainly industrial city today; It got city right in 1306. Today, about 8k people live there.
Should we mention Lenzburg has the biggest Prison in Aargau?
Splendid stuff. No reason not to add the prison fact, as long as we can cite it ?The Rambling Man (talk) 16:10, 7 October 2008 (UTC)
A quick search revealed: Stating there is a prison near Lenzburg is probably easy, though I did not find anything that it was the biggest in Argovia. Also, the refs I find are usually German language...--Eptalon (talk) 16:38, 7 October 2008 (UTC)
The enWP article has a 2010 population ref, , possibly update according to enWP?

Most importantly, the Geography, History, Places of interest, Economics, and Transportation sections are all unreferenced. Albacore (talk·changes) 21:19, 28 June 2011 (UTC)
As for this unreferences: In the references section, there is a part saying "General". Things from economy, history, etc can be found there. This should be enough. It is just not mentioned with the number next to the sentence directly. -Barras (talk) 12:13, 30 August 2011 (UTC)
