Popular Baby Names

I am a COMPLETE anorak where it comes to statistics so really found this exercise interesting! I looked at the top 10 baby names for boys (girls will follow shortly!) for 4 different years - 2001, 2006, 2011 and 2016. Here they are:

A few interesting observations:

• 6 names (Jack, Sean, Adam, Conor, James and Michael) have been in the top 10 for all of the 4 years
• David, Dylan and Cian seem to have reduced slightly in popularity more recently 
• Daniel was not in top 10 in 2001 but has been there for the other 3 years
• Ryan, Harry & Alex entered top 10 in 2011 but didn't feature last year
• Noah and Oisin have become popular more recently, featuring the top 10 in 2016 but not in the other 3 years which I looked at. 

And just in case you're interested, the 5 LEAST popular names for each of the years were as follows:

2001: Calum, Bobby, Sebastian, Daithi, Patryk 

2006: Filip, Glen, Kacper, Szymon, Jayden

2011: Glen, Ian, Neil, Emmanuel, Keith

2016: Zach, Jason, Sebastian, Dara, Isaac
