Some tidbits from a good article from Albert Mohler: https://www.ligonier.org/learn/articles/problem-delaying-marriage/
Tellingly, secular authorities in the culture are now expressing worry about the delay of marriage among young Americans. When Time magazine is concerned about young Americans not getting married, Christians must be doubly concerned.
Study after study reveals that young Americans are achieving adulthood, if at all, far later than previous generations now living.
Why is this important to us all? A stable and functional culture requires the establishment of stable marriages and the nurturing of families. Without a healthy marriage and family life as foundation, no lasting and healthy community can long survive.
And we must encourage young Christians not to delay marriage, nor to marry in haste, but to make marriage a priority in the critical years of young adulthood. The Christian church must encourage young Christians toward the goal of marriage and must be clear about the necessity of holiness and obedience to Christ at every stage and in every season of life.
