According to the Congressional Budget Office (CBO), S.744, also known as the Gang of Eight Bill, would increase legal immigration into the United States, thus increasing the foreign-born share of the US population to 15% by 2020. This new statistic surpasses the 1890 high of 14.8%. Furthermore, officials predict the foreign-born population will reach 17% of the population (or 65.2 million) in 20 years, by 2033.

More CBO findings include:

• The record high of 15% will mean the foreign-born share of the population will have tripled over the past 50 years, from 4.7 in 1970
• The rate of growth in foreign-born people living in the U.S. has never been so high
• The size of the foreign-born population increased from 9.6 million in 1970 to 31.1 million in 2000. And will reach 65.2 million people by 2033
• Based on CBO projections, the total size of the U.S. population will reach 351.8 million in 2023, should the bill pass
• The foreign-born population percentage is not expected to stabilize by 2033, but continue to increase significantly after that date

These findings elongate the discussion on the impact of the bill, giving numbers to the debate on its impact on the job market, absorption capacity upon America’s roads, bridges, schools and power grid. Other questions include the increase’s ability to change the aging of American society. Furthermore, as the U.S. population grows to include more non-U.S. born residents, its culture will continue to change, amalgamating to the incoming ideas, ideals, customs and expectations of others and becoming more of the Melting Pot it is known to be.

根据美国国会预算办公室(CBO)S.744，也即“八人帮”草案，它有可能增加大量来美合法移民，因而至2020年，外国出生美国公民将达15%。这个统计数据超过了1890年规定的最高14.8%。此外，美国官员预测，外国出生人口将在20年内，即到2033年的，达到17%的总人口比例（约6520万）。

更多国会预算办公室（CBO）调查结果包括：

• 15%的比例意味着外国出生的居民人口比例将在自1970年起的50年内翻三番，1970年外国出生的居民人口仅4.7%。
• 居住的美国的外国出生人口增速迄今为止最高；
• 外国出生的居民从1970年960万的人口规模增加到2000年的3110万。到2033年，预计将达到6520万；
• 根据国会预算办公室的预测，如果该议案通过的话，美国人口总数在2033年将达3.518亿；
• 外国出生的居民比例不会在2033年就停止增长，仍将会持续保持增长。

这些调查结果会在议案辩论期间综合考虑，对未来就业市场、美国道路、桥梁、学校和电网等的基础设施等都将产生影响。其他如改变美国社会的老龄化问题也都将在考虑范围。 此外，随着美国人口将吸纳越来越多的非美国出生居民，美国文化也将继续改变、融合传入的不同观点、思想、习俗及预期，越来越典型体现其“大熔炉”特色。
