The following is data from the American Community Survey. It uses estimates from data gathered between 2011-2015. Using this 5 year span increases the precision although currency is sacrified. The larger span is necessary to have valid information for smaller geographic regions.
This map shows counts for children under 5 (non-inclusive). It splits geographic regions into the smallest available units for this data, called block groups. Clicking a region will display the value.
In order to get more fine-grained age groups, it is necessary to give up some geographical specificity. This map shows census tract counts for children in 3 groups: under 3, 3 to 4, and 5 years. It includes all income levels. Data for smaller subregions is not available for this granularity of age.
This map shows counts for children under 6 (non-inclusive) with various ratios of income to poverty level in the past 12 months. Data for smaller subregions or more fine-grained age groups is not available (though we estimate them in the map following this).
While there is no data for ratio of income to poverty level for smaller age ranges than “under 6”, we can make a guess based on the proportions of population counts for the groups “under 3”, “3 to 4”, and “5 years” from table B09001 (populations under 18 years ago age). The populations for these tables is slightly different. For ratio of income to poverty level, the population is people for whome poverty status is determined. For population it is people under 18 years. Thus some of the people represented in population counts are not represented in counts for ratio of income to poverty level. Overall, the difference between counts for ages < 6 for Clatsop county is 2526 - 2494 = 32 (1.3% missing), and for Tillamook county is 1534 - 1494 = 40 (2.6% missing)
This map shows mobility for children under 5. It is based on where the child lived 1 year prior to the time of the survey.
