There are loads of factors at play, to lay the blame of this demographic trend solely on bike-centric policy is, if I’m being very very generous, lazy. Since it’s the telegraph, about a foreign city, I would assume it’s disingenuous.
The article doesn’t even call out bike centric policies:
> “It is the result of a quarter-century of policies that have made life harder for families and the middle class. Construction work, difficult access to nurseries, skyrocketing rents, and social housing shortages have pushed Parisians to the suburbs or provinces.”
The “worst” callout in the article is triple parking fees for SUVs.
Oh.
Anyway.
It looks like there are loads of factors at play and I wouldn’t trust assigning blame to just one, especially when your supporting article only kinda sorta touches on that factor.
My message starts with "it's a reason among others".
And bike-centric policies have led the city to invest in bike lanes, rather than in the aging public transport and to remove surface parking, making it almost impossible to own a car if you have a family. All of this is in the article that I linked.
An unexpected casualty of this is that it's now complex to get trade workers to come to Paris for construction jobs, and, funnily enough, public works to build bike lanes are more costly as trucks and workers spend a lot of time in the traffic now.
If you had a source for those claims, it might be interesting.

First chart shows that average speed for cars have decreased steadily. For surface parking a simple google search will help you find it.
The part that I don’t see is how this is actually a significant causal factor driving families out.
