In the US there is something in the claim of the original poster:
canonlaw.info/a_annulments.htm
The main point is that
In the early 1960s, about 300 declarations of nullity came from the United States each year; today that annual figure has grown to over 60,000.{/QUOTE]And that is due to a number of circumstances, among them changes in the law between the 1917 Code (in which there were extremely limited grounds for a decree) and the 1983 code, which acknowledged the vast increase in information concerning psychological issues, among other things, and the vastly increased understanding of what the term “intent” actually meant and consisted of.

and also that over 80% of the cases the nullity is approved.
This, with no explanation is a patently false statistic. The only records of approval or disapproval are those in which the case actually gets to a decision. That is, it is not a record of how many approvals are given for the number of cases filed; it is only for cases completed. and even that statistic - % of decrees granted of all cases filed would not tell the full story, because it would not cover the cases that are started (and by this, I mean at the minimum an inquiry with a priest or other person in a position to move a case forward and the number of decrees granted.
CARA keesp statistics on various Church issues. According to CARA, 7% of cases started (not filed - started, which is before a case is filed) are ulitmately granted a decree of nullity, 8% of those started do not receive a decree of nullity (the greater majority either not being filed, of being filed and withdrawn), and 85% of marriages ending in divorce never even seek a decree.
As far as I remember the popes (either Blessed John Paul II and Benedict XVI) questioned the prudence of the American diocesan courts
John Paul twice took Canon lawyers to task (along with the tribunals) because there was fairly clear evidence that some cases were being improperly decided. Undoubtedly some of those cases would not ultimately have ended in a decree; but that is not evidence that all cases decided on the grounds he was objecting to would not have been granted on other grounds, had the case been more carefully prepared and tried.
The extremely disturbing is the huge difference between the American cases and the other parts of the world. I know in details only the Hungarian practice, but over there the annulment is extremely rare, over here the denial is rare.
This issue has been vetted elsewhere, and in fact Rome has addressed the rest of the world in that they - the rest of the world - are not adequately addressing the issues. If you have a chancery that doesn’t even own an operating fax machine, if you don’t even have a tribunal, if you don’t have adequately trained Canon lawyers to handle matters, if you don’t have a properly trained clergy to address the issues, if you have divorce laws that make it anywhere from very difficult to almost impossible to get a divorce, then the issues of nullity of a marriage are simply not going to be addressed. That does not mean that the rest of the world has fewer invalid marriages; it only means that the issues are not being addressed.
In addition there are cultural issues; in some areas of Europe where only maybe 5% of Catholics attend Mass on a regular basis, the statistics are probably significantly higher of people not even seeking a decree - they don’t care. People have to care a minimum amount to even ask the question, let alone go through the process.
