You’ve probably never heard the phrase “first lady” before.

It’s one of the most common, and it’s a term that is used to describe someone who has not yet been married, but whose marriage to a man or woman has not ended in divorce.

In some parts of the world, first lady is synonymous with royalty.

But in the United States, first ladies have been a rarity, and the number of women holding that title has been steadily declining for decades.

Today, only about 4% of all US first ladies are women, according to the United Nations. 

A new study shows that women of all ages, race and class are more likely than men to be in the church, and that they are not only more likely to be ordained, but they are also more likely in the workforce, in higher educational institutions and in the professional ranks. 

According to the study, which surveyed more than 12,000 women in the US, first wives are significantly more likely as women to have college degrees than their husbands. 

And women are more than twice as likely as men to hold a bachelor’s degree or higher. 

“First ladies tend to be less well-educated, and more likely that they have attended college than their husband,” said Sarah Smith, a senior fellow at the Urban Institute and co-author of the report. 

The number of first wives is down since the 1950s, but the percentage of women in higher education is also down, Smith said.

The report, which is based on data from the American Community Survey and the Census Bureau, found that in 1950, 19% of women ages 15 to 44 had college degrees.

By 2010, only 12% of that group had a college degree. 

More women than men were married in the 1950, and today, only 5% of first ladies and 7% of their husbands are married. 

Smith said that the gender gap is due to the fact that women have been underrepresented in church leadership positions. 

“[Women] are often not ordained, and are not necessarily ordained as women,” Smith said in a statement. 

For example, women are less likely to serve in senior leadership positions, and have been sidelined in church governance and governance committees, Smith explained. 

Women are also less likely than their male counterparts to have a college education. 

In the past, Smith noted, men were ordained in higher numbers.

Today that number is down to about 3%. 

“In the 1970s, men had more authority and prestige in church, but now women are not doing that.

In fact, women now hold fewer leadership positions,” Smith wrote. 

While the number and distribution of women are changing, there are still large disparities in church attendance and involvement. 

As of 2011, about 37% of adults in the country reported attending church, while less than 6% of the population said they were active members, according the Pew Research Center.

The proportion of adults who attended church was lower for African Americans and Hispanics than for white adults. 

This was largely because African Americans were less likely and white adults were more likely, Smith added. 

But in the past two decades, the proportion of Americans who reported attending a church in the 1990s has increased significantly, to 27% in 2009 from 16% in 2000. 

Among those who were active in church in 2009, more than a quarter (26%) were women, up from 14% in 1990. 

That is partly because of the increase in women who were more involved with church and other activities.

Women who were involved in church and church-related activities had more educational and professional qualifications, according in the study. 

Although the number, size and composition of women have decreased over the past decade, the gap between men and women is growing.

In the United Kingdom, for example, the number was 20% in 1950.

In 2015, it was 26%.

The US has the highest number of female first ladies, according a study by the Pew Forum on Religion and Public Life. 

Over the past half century, the percentage among women in leadership positions in the Church of Jesus Christ of Latter-day Saints has declined by 8%, while the percentage for men has increased by 9%. 

The study also found that the number in the priesthood has also declined since the 1960s.

But among all men, the priesthood percentage increased from 19% in 1960 to 22% in 2015. 

When it comes to the religious landscape, women in some churches are in charge of church policy, while men are involved in the administrative process. 

First ladies can take the lead in leadership of congregations, while their husbands serve as bishops, priests and deacons, Smith stated. 

What does it mean to be first lady?

First ladies are generally considered the first wives of the United State, according this definition. 

To be first wife, a woman must have been married at least once to a US president or vice president, a governor, an attorney general, a
