Light Pollution Over Time

I read a comment (elsewhere on the web, not this forum) from someone saying they thought the view of the night sky in their city had improved. I suspect this was from someone who is not a regular observer. I can’t say that this is my experience, but it got me thinking - are there any reputable surveys/statistics that show comparison over time?

I did have a quick look, but couldn’t see anything obvious. I did, however, find this link, which had me puzzled even more, especially as it was tagged onto the website for a producer of blinds and shutters. The sources seem to imply the CfDS and the International Dark Skies Association we’re referenced. I appreciate it’s specifically talking about skyglow, but at the same time implying this may be reducing in the UK.

I’d love to hear your thoughts on this.

Best wishes, Jeff.

I can only see the 2025 map. No scrollbar for me. Pity.

I think that skyglow gets worse and worse here, however, my eyes are also not so good.

It may be that the constant building work just increases housing density.

I see no evidence for any reduction in skyglow over time.

The LEDs are massively overbright and 'security' lights breed like rabbits. :(
