A report compiled by Statistician and Ph.D. candidate Sam Monfort last month revealed that UFO sightings in the United States had reached an all-time high in recent years.

But in which state have aliens found themselves feeling the most at home?

California, apparently.

In total, there have been more than 120,000 unidentified flying objects spotted across the United States between 2001-2015, according to a new book called "UFO Sightings Desk Reference: United States of America 2001-2015."

During that time, the Golden State saw almost 16,000 of them, with Los Angeles serving as the most frequent reporting location.

There were apparently 3,200 UFO sightings were reported in the county alone -- outranking 40 other individual states in sightings.

The book's co-authors, UFO experts Cheryl Costa and Linda Miller Costa, dubbed their 374-page guide "the first book of its kind."

In it, Costa and Costa present a data analysis for every reported sightings of unidentified flying objects reported by individuals during the first 15 years of the 21st century.

Cheryl Costa, an upstate New York resident and military veteran, says her interest in the book's subject matter stems from a personal experience. She claims to have seen her first UFO at age 12.

The now-retired information security professional spends her time speaking at conferences like the International UFO Congress and the the Mutual UFO Network Symposium.

She and her co-author say they hope their book can shed some light on a subject that "the government has claimed no interest in" and "the press and media either ignore or ridicule."

If you want to see how your county's number of reported alien visitations stacks up against the rest of the nation, you can pick up a copy of "UFO Sightings Desk Reference: United States of America 2001-2015" on Amazon.
