Officials: More Migrants Caught at US Border Than at Any Time Since 2000
United States officials caught 171,000 people trying to illegally cross the U.S. border with Mexico last month. That is 178 percent more than in February.
Most of the people are trying to escape difficult conditions in Central America and Mexico.
The Reuters news agency reports that more people tried to cross the border in March than at any time in the last 20 years.
About 99,000 of the total were single adults. The rest included almost 19,000 children traveling alone and about 53,000 family members traveling together.
Children who arrive at the U.S. border alone are not sent back immediately. They are housed in "processing centers." However, the centers are designed for many fewer people and now are overcrowded.
As a result, the U.S. government opened emergency shelters in Dallas, Texas and San Diego, California. But those are also getting full.
President Joe Biden has said the "vast majority" of families who arrive together at the border are being sent back. However, information from U.S. Customs and Border Protection shows that might not be the case. More than half of the 19,000 people who arrived as part of family groups were not sent back in February. Many were released into the U.S. and were required to appear at an immigration court at a later time.
Reuters also looked at documents from three separate days in March that showed fewer than 14 to 16 percent of family members were sent home on those days.
Sarah Peck is a spokeswoman from the U.S. Department of Homeland security. She said, "one day or week of statistics doesn't reflect the full picture."
She added that it is still the government's policy to send families away. However, Mexico, the country from which the migrants entered the U.S., is not always able to receive them. So they are sent to an immigration court.

美国官员上个月逮捕了17.1万名试图非法越过美墨边境的人 。这比2月份增加了178% 。
其中约有9.9万人是单身成年人 。其余越境者包括近1.9万名无人陪伴的儿童，以及约5.3万名一起出行的家庭成员 。
独自抵达美国边境的儿童不会立即被遣送回国 。他们被安置在“处理中心” 。然而，这些中心原本旨在供少量人使用，现在已经人满为患 。
因此，美国政府在得克萨斯州达拉斯和加利福尼亚州圣地亚哥开设了紧急避难所 。但这些场所也将达到容量上限 。
美国总统乔·拜登表示，一起抵达边境的“绝大多数”家庭将被遣送回国 。然而，来自美国海关和边境保护局的信息表明，情况可能并非如此 。2月份，以家庭为单位抵达的1.9万人中，有半数以上没有被遣返 。许多人被放进美国，并被要求稍后在移民法庭出庭 。
莎拉·佩克是美国国土安全部的发言人 。她表示，“一天或一周的统计数据并不能反映全部情况 。”
她还表示，政府的政策仍是遣返家庭成员 。然而，这些移民往往通过墨西哥进入美国，但墨西哥并不总能接收他们 。因此他们被送往移民法庭 。
