In the US in my region (midWest rural) there isn't any growth. Kids getting baptized, some foreign language growth (I hear) but besides that there are very few converts like in the pre '1995-or-so' days. I believe the increase on publishers that are being printed are due to:
1) making it easier to report time. 15 minutes at a time is allowed, and both parents can report time for their bible studies at home with kids. and
2) encouraging, reaching out to, former publishers who have gone inactive in service but still attend meetings for family reasons. There are many, many people in each congregation like that who have started reporting again, maybe just an hour or two.
The result is an increase in numbers of publishers, but I wouldn't call it growth.
