And yet the actual numbers show that Christianity is in decline in the USA.

Indeed - the actual data and truth of the matter are entirely distinct from the articles editorial line, which is, of course, wishful thinking on the part of its authors.
So the actual data, shows without any doubt, that christianity is declining in the US as a proportion of the population. With no religion on the rise. Pretty well the same as we've been seeing in the UK for some while, and other european countries. I suspect the US is where the UK was perhaps 30 years ago but will almost certainly follow the same trend over the next few decades, as the reasons will be the same - each generation being less religious than the previous one.
And these data nail the hoary old myth that is 'Ah but people get more religious as they get older' - they don't. In fact these data show clearly that people get less religious as they get older. The survey looked at religiosity amongst people in 2009 and 2019, grouped by their data of brith. So they are comparing the same people - they were just 10 years older in 2019. Did they get more religious as they got older? Nope - for every group (from those born 1928-45, through to those born in 1981-96) they got less religious as they got older, with greater proportions saying they were unaffiliated and fewer saying they were christian in 2019 compared to 2009 when they were 10 years younger.
