### Why can't I find my ZIP Code?

QuickFacts does not contain data for Postal ZIP Codes. Only States, Counties, Places, and Minor Civil Divisions (MCDs) for Puerto Rico and the United States with populations above 5000. When you search via a ZIP code QuickFacts provides a list of near matches for the geographic types contained within the application. These near matches are created from US Census Bureau ZIP Code Tabulation Areas (ZCTAs) which are generalized area representations of United States Postal Service (USPS) ZIP Code service areas.

Explore Census Data for ZCTAs data and surveys.

### What is QuickFacts?

QuickFacts is an easy to use application that provides tables, maps, and charts of frequently requested statistics from many Census Bureau censuses, surveys, and programs. Profiles are available for the nation, all 50 states plus the District of Columbia and Puerto Rico, and all counties. Cities and towns with a population of 5,000 or more are also included.

### What are the recommended browsers?

IE11+, Chrome, Firefox and Safari (Safari on MAC only)

### How do I begin?

QuickFacts begins in TABLE view with data shown for the UNITED STATES. You can change to MAP view, CHART view, or the DASHBOARD view, that shows all three views at once.

### How do I “Enter state, county, city, town, or ZIP code?”

Begin typing the name of the geography or ZIP code. After the second character, a list of choices will appear on the drop down. Locate and select your area by single-clicking the mouse or by using the up and down arrows and then pressing the Enter/Return key. The Enter/Return key may also be used if only one geography appears or your highlighted selection is at the top of the list. This becomes one of your selected geographies and is added to the TABLE in the first data column, moving UNITED STATES to the second data column.

### How do I “SELECT A FACT?”

Simply click on SELECT A FACT to show the dropdown list, which is grouped by topic. Scroll down to highlight the FACT you want and click on the FACT to select it. In addition, you can double click on the row of the FACT in the TABLE.

### How do I narrow the results?

          - In TABLE view, click ALL TOPICS and select the topic you want. The table view will show only facts within that topic. To view all facts again, select ALL TOPICS.
          - In MAP view, you can further narrow results down to counties, county subdivisions, or places by selecting a geography color-coded circle and a small pop-up window appears with further area selections to view. For example, if your selected geography is a city, and you chose a city in that state on the map, you will have the option to Add this geography to your table, view at the United States level or view the counties in that state.
          - In CHART view, you can toggle between all geographies at the same level as your selected area or those you have selected by using the ‘Show selected locations' checkbox.
          - In DASHBOARD view, you can narrow down only what facts are showing by using the ALL TOPICS dropdown, as indicated above.

### In TABLE view, how many geographies can I see?

TABLE view allows six geographies in the table. To add additional geographies use the search box. As you add geographies, they are added to the TABLE in the first data column, moving other geographies to the next column to the right. If there are more than one geography present, you may delete any geography by clicking the  icon. An orange circle on the TABLE icon indicates the total number of geographies currently selected. This is visible throughout the application above the data views.

### In MAP view, how many geographies can I see? Can I zoom in and see data?

There are 3 additional controls in addition to the zoom in/out and full screen controls:        
          - Left Border Slide-out - Allows the user to quickly move to and remove their selected geographies.
          - Switch Control in the upper right corner - Turns on the ability to select geographies across state boundaries.
          - Toggle Button in the upper right corner - Toggles view between Townships and Places.

Clicking on a geography opens an info window. Within the info window you can:        
          - Add or remove a geography to your selection.
          - View the current selected fact's value and footnote notations.

The new switch and toggle button are present on the map only when needed. All new controls will be pointed out to the user with a "NEW!" tooltip when first presented to the user. Hovering over the new control will give the user a description of the control's function as well as its current status if applicable.

Changing geography level is accomplished by zooming in/out. The progression as you zoom in is: States, Counties, Places & Townships. When zoomed into Places & Townships level a toggle button will be available within the upper right map controls to swap between the two.

When you select the MAP view icon, you are given a choice from your selected geographies to view one on the map. Once you click on a geography, you will see your selected geography outlined in red and all geographies at the same level. For example, if you selected a county, you will see all the counties in that state.

Geographies with numeric fact values are placed in ascending order and distributed into five groups containing the same number of geographies. The geography groups are then shaded from cyan (lowest values) to dark cyan (highest values). The value range for these groups will depend on the fact and geographies that fall within the group. Geographies with non-numeric fact values and footnotes are shaded with colors other than cyan and assigned to a specific footnote.

When viewing the entire US there are icons for Alaska, Hawaii and Puerto Rico in the corners that allow you to focus the map directly on those locations. When the map focuses on one of these locations their associated icon changes to the 48 contiguous states an allows you to reset the map to view the entire US.

### In CHART view, how many geographies can I see? Can I see data?

When you select he CHART view icon, you are given a choice to ‘View Selected Locations' or choose one of the selected geographies. If you chose ‘View Selected Locations', you will see a chart for all selected geographies. If you only have one geography selected, the chart will open with this geography along with all sibling geographies. For example, if you have selected a state, you will see all the states, plus the District of Columbia and Puerto Rico. Hover over or click on each bar in the CHART to see the actual data value.

### In DASHBOARD view, how many geographies can I see?

DASHBOARD view is a combination of all three views. 
          - When you select the DASHBOARD view icon, you are given a choice to create a dashboard for one of your selected geographies.
          - DASHBOARD's TABLE shows fact data only for one selected geography.
          - On DASHBOARD's TABLE you cannot add a geography.
          - DASHBOARD's CHART shows data for the selected geography and all its siblings, same as the expanded CHART view. You can add and remove a selected geography from the dashboard chart. Selected Locations checkbox is not available on the DASHBOARD's CHART.
          - The DASHBOARD's MAP shows data for the selected geography and places at the same level, just as in the expanded MAP view.

### Where can I get data for other levels of geography, like metropolitan areas? 

While not available in QuickFacts profiles, there are a number of sources on census.gov for data about metropolitan areas.

### How can I browse more datasets for my selected location?

Whenever you see an orange magnifying glass , click it for all the detailed links to other datasets.

### Can I share data from QuickFacts?

Yes. The MORE menu item opens a popup where you have options to PRINT, download a CSV, EMAIL, EMBED, and post on TWITTER and FACEBOOK.

### What do these icons mean and what happens when I click them?

Click for additional information such as Sources, Definitions, and sometimes Margins of Error, or More Information.      

Click for all the detailed links to other sets of data about the respective geography.      

Click to set the application to its default state. This will remove all selected geographies and begin a new search. Your prior searches and results will not be saved.      

Click to open the popup for all the download and share options.      

Click this icon to delete a geography.
