Welcome to the Clark County, NV Childhood Lead Surveillance Dashboard

The dashboards and data available through this application are the result of an ongoing collaboration between the University of Nevada, Las Vegas (UNLV) and the Southern Nevada Health District (SNHD). The goal was to launch a geographically specific data visualization tool that provides lead testing rates and lead exposure risk zip code in Clark County, NV. The purpose is to provide surveillance of elevated blood lead levels (>=5 ug/dL) in children (age <6 years old), which is currently targeted by the Nevada Childhood Lead Poisoning Prevention Program (CLPPP) funded by the Centers for Disease Control and Prevention (CDC).

Understanding the Data

The data used in this application was gathered from the following sources:

  • Commercial Laboratories
  • Healthcare Providers

  • The Nevada Administrative Code Chapter 441A requires healthcare providers and laboratories to report known lead exposures and elevated blood lead levels to SNHD. The purpose of reporting and surveillance of elevated blood lead levels allows SNHD to monitor blood levels throughout Clark County, NV and decrease lead exposures by identifying the source of lead involved, identifying sensitive populations exposed to lead, identifying sensitive occupations in which lead particles may be brought into the home, and educating the community about sources of lead as well as limiting lead exposure.

    The data available through this application can be used to assess relative testing rates among children <6 years of age by zip code throughout Clark County, NV. The lead testing rate is an estimated percentage of children <6 years of age living in a given zip code who screened for lead compared to the estimated total of children <6 living in the same zip code.The lead exposure risk index can be used to assess and identify zip codes of high and low risk for lead exposure, based on two well-known identified risk factors; age of housing and percent poverty. It is important to note that the lead risk exposure index does not provide us with where lead poisoning is occurring, but what zip codes in Clark County, NV have a greater potential for lead exposure based on age of housing and poverty. The lead exposure risk does not take into consideration occupation, hobbies, and/or imported goods which may introduce lead particles into a household.

    Using the Dashboard

    For optimal compatability, please use the Chrome or Firefox Web Browsers.

    Explanation of icons/settings when navigating the site:

    - Collapses or 'hides' the sidebar. For some screen sizes (i.e. 1078x768), collapsing the side bar may improve viewing of the dashboard. If not, we recommend adjusting your browser window.

    Settings: - Settings for graphs or tables. Each window has an analytic focus and is customizable by clicking the 'settings' tab in each window. You will have the option of selecting:

  • Data Source
  • Year to display (all graphs default to the most current year of data)
  • Data Indicator (please review the Data Definitions page)
  • Geography (depends on the graph)

  • Clicking, Hovering, Scrolling, & Dragging All of the graphs and maps are dynamic. Which means they respond to clicking, hovering over, scrolling or dragging elements. The maps will zoom by scrolling, move by dragging (like Google Maps), and will display data for colored geographic areas upon clicking. All of the graphs respond to clicking and dragging. You can reset the graphs by double-clicking. All of the bar charts will display data values by hovering your mouse over the bars. Our advice is to explore the graphs in order to achieve the rendering of the data desired.
