My research question will be "Did the frequency of bird strikes in the aviation industry decrease in the aviation industry from 2010 to 2020?". (It can be changed if you have another idea for it)

You can use both types of strikes reported or just total strikes reported data only.

Percentage Damaging strikes damaging Year Total strikes strikes vs. total reported reported strikes 2010 9,889 595 6.0% 2011 10,104 542 5.4% 2012 10,903 613 5.6% 2013 11,406 609 5.3% 2014 13,683 587 4.3% 2015 13,788 622 4.5% 2016 13,353 589 4.4% 2017 14,788 667 4.5% 2018 16,222 708 4.4% 2019 17,358 739 4.3% 2020 11,605 462 4.0%
