Until its dissolution NFISD was the poorest district in Harris County. During a period when NFISD received $1,711 per student in property taxes, nearby Deer Park Independent School District received $7,021 per student despite having a lower tax rate. As of 2003 the NFISD attendance zone had very little industry. In 2006 the area within NFISD had the lowest property value per student ratio in Harris County, and less than half the average in the state. Within the district, in 2006 the typical single-family house was appraised at $51,106 ($ when adjusted for inflation). 42 of the 15,637 houses within the NFISD boundaries had an appraised value greater than $200,000 ($ when adjusted for inflation).
