1. Nearly 600,000 students in Texas are not English-proficient, out of 5 million in the school population.

These numbers can be found on this document produced by TEA.

2. His district's superintendents say it costs 30 to 40 percent more to educate a non-English-proficient student, about $4,000 more.

This was a statement to Dan from his supers. Call Alejandro Morua with Cy Fair ISD...

3. Seventy percent of babies born at LBJ Hospital are born to mothers not here legally (I think we checked this one already).
Harris County Hospital District gave us these numbers and percentages of births to illegals:

 

Undocumented Immigrants born at LBJ General Hospital by Fiscal Year:

2007  3,472  72.80%

2008  2,996  70.89%

2009  2,389  58.91%

2010  2,418  63.33%

 

4. According to TDCJ, nearly 15 percent of inmates convicted of DWI are illegal immigrants or people lacking US citizenship.

We got these numbers from TDCJ:

Prison offenders whose offense of record is DWI:          5,943

Of those, the number claiming foreign citizenship:          914

(TDCJ says that the number claiming foreign citizenship is statistically indistinguishable to those who are here illegally.)

Can you guide me to the basis for these numbers?

Thanks.
