Google released its annual diversity report on Thursday, but there was little improvement over the previous year.

The number of women in technical roles increased to 20 percent from 19 percent in 2015, according to the report. Women also saw a one point gain in leadership and now hold a quarter of those positions. Despite these developments, women still make up only 31 percent of the company's employees.

Latinos also saw a slight uptick to 4 percent in 2016, from the 3 percent back in 2015. But black employees remained flat at 2 percent. The percentage of Asian employees grew more than any other group: Asian staffers now make up 35 percent of the company, from 32 percent in 2015, and 27 percent of leadership roles, an increase of 2 percent from the previous year.

Lastly, Caucasian employees dropped to 56 percent from 59 percent. Silicon Valley companies have recently faced intense criticism for their lack of diversity both in overall staff positions and in leadership roles. While there were slight gains over last year, there is still room for improvement.

Google also announced on Thursday that it has hired Danielle Brown, Intel's former head of diversity, as its VP of diversity. Starting in July, she "will be responsible for managing our diversity and inclusion strategy, partnering with our senior executives on this vital work," Google wrote in a blog post.
