  1. In 2010, Brooklyn (1,621), followed by Queens (860) and the Bronx (752), had the most carbon monoxide incidents. Manhattan,however, had the highest rate per 100,000 buildings (12.2%) of carbon monoxide incidents in 2010. Queens (2.2%) and Staten Island (2.3%) had the lowest rates of incidents per 1,000 buildings in 2010.
    2. In the graph below, the medium level of poverty does not always correspond with the middle number of carbon monoxide incidents. The highest level of poverty, however, does correspond with the highest level of carbon monoxide incidents but the lower levels and medium levels of poverty do not always follow the anticipated pattern that the higher the level of poverty, the higher the number of carbon monoxide incidents. 
    3. The correlation between the percent of households rated good or excellent with the number of carbon monoxide incidents suggests that the better quality of the housing structure, the less carbon monoxide incidents occur. Perhaps the better quality housing and neighborhood structure and appliances (such as the furnace), the smaller the chance of carbon monoxide incidents occurring.
    4. From 2004 to 2005, all boroughs experienced an increase in the number of carbon monoxide incidents.  Staten Island experienced a less significant increase than the other boroughs from 2004 to 2005 and then appears to have remained rather stable. After their increase in 2004-2005, the other boroughs appeared to have gradually decreased until another gradual increase in 2008. The carbon monoxide incident levels appear to be at a slightly higher level in 2010 than in 2004 (most notable difference in Brooklyn).
    5. Rate of carbon monoxide incidents per 1,000 buildings appear to increase the more north one travels on Manhattan and then gradually decrease the more north one gets in the Bronx. Staten Island had a low number of incidents (light yellow). Queens also had a low number of incidents, with the largest being in the middle of queens (more orange than surrounding areas). Brooklyn experienced a range of 1 to 15 buildings per 1000.
