Global estimates of modern slavery that include those living in forced marriage or sexual exploitation are crucial in informing policy and uncovering overlooked groups of victims.

The recanvass of votes in the Kentucky gubernatorial race highlights the importance of key scientific evidence regarding election security and integrity, specifically the need for paper ballots and statistically sound post-election audits to inspire confidence in election results. In a race that may be determined by a few thousand votes, election officials cannot conduct a recount because Kentucky’s voting machines are entirely electronic and paperless. Instead, Kentucky county election officials will submit certified vote forms based on totals tabulated by the voting machines themselves and absentee ballots.

The North Carolina Board of Elections voted to certify voting systems based on paper ballots. The following is a statement from Michael Fernandez, director of the American Association for the Advancement of Science’s Center for Scientific Evidence in Public Issues.

The evidence shows that the routine use of statistically driven risk-limiting audits would be the most effective way to ensure the accuracy and security of elections. With the increase in the use of technology to record and tally votes, auditing election results before they are certified can provide additional assurance of the integrity of the results.

Today many voting systems are outdated and vulnerable to interference or errors and some states and counties lack the funds to replace them. A lack of regular, ongoing funding for election security remains one of the primary concerns of election officials. Despite these challenges, election administrators across the country are working to address election security issues and many recently replaced outdated paperless machines and moved to using paper ballots.
