  • Keeping Nita’s intro to GIS in mind, let’s look a North Port in a bit more detail. We’re going to look at five different boundary systems: 1) zip codes 2) school attendance zones 3) Voting Precincts 4) census boundaries and 5) neighborhoods.Looking at boundary systems is important because decisions are often made according to different boundaries. It’s important for us, as residents, to know understand our boundary systems are because they help us to make informed decisions about our place and understand when decisions get made about us within a place.
  • Keeping Nita’s intro to GIS in mind, let’s look a North Port in a bit more detail. We’re going to look at five different boundary systems: 1) zip codes 2) school attendance zones 3) Voting Precincts 4) census boundaries and 5) neighborhoods.Looking at boundary systems is important because decisions are often made according to different boundaries. It’s important for us, as residents, to know understand our boundary systems are because they help us to make informed decisions about our place and understand when decisions get made about us within a place.
  • Let’s start with zip codes because…(a lot of times decisions like where to allocate resources are made by looking at differences across zip codes). (8) Zip codes on North Port out of (27) in Sarasota CountyNote that some extend beyond the City of North Port boundary.Zip codes are huge, extend beyond county boundaries, are not how we live in relation to one another.
  • Let’s look at a set of boundaries that relate a bit more to how we live. For kids at least, boundaries that relate to school attendance zones reflect more how kids come together with fellow people in North Port on a daily basis. There are (27) different elementary school attendance zones in Sarasota County.North Port includes (7). Some extend beyond NP City Boundaries.NP is unique in that some are part of Charlotte County School District. You will find the maps of Middle School and High School Attendance Zones in your packets.BUT, SAZs don’t relate to everybody (really just kids) and not all kids in the area go to the designated school and these geographies are still larger than how we connect with fellow community members on a daily basis.
  • There are other aspects of daily life that correspond with different sets of boundaries. Let’s take civic engagement in terms of voting. In this case the boundaries that are relevant are voting precincts and districts.These (fall within city boundaries). There are (155) in the county.There are (10) within the city. In your packet, you will also find a map of boundaries that relate to public safety (police beats).
  • The Census is a survey conducted every 10 years (starting in 1790) by the US Government in order to count the number of people living in the US. The Census count is the basis for congressional redistricting, but Census data is also used to make decisions about the distribution of funds for government programs such as Medicaid; planning the right locations for schools, roads, and other public facilities; helping real estate agents and potential residents learn about a neighborhood; and identifying trends over time that can help predict future needs. Most Census data are available for many levels of geography and boundaries, including states, counties, cities and towns, ZIP codes, census tracts, block groups, and blocks. A census block is the smallest geography: the block you live on. This is the most local data available from the Census. Block sizes and shapes vary depending on the geographic area. These get updated every 10 years.A census block group is a cluster of blocks. BGs generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. A census tract is a cluster of block groups. Census tracts generally have between 1,500 and 8,000 people, with an optimum size of 4,000 people. Census tract boundaries are stable and do not change from census to census which allows us to compare data across censuses. Most data at the census tract level doesn’t allow us to see understand what’s going on very well.
  • Neighborhood boundaries are not always the same, depending on with whom you are speaking.This is a map of North Port neighborhood boundaries from the City of North Port. You’ve now heard Robin and Dorothy speak about their neighborhoods here in North Port. What you might notice is that the neighborhood boundaries they’ve shown do not correspond with this map.
  • These three maps show different sets of neighborhood boundaries from different places:City of NPRCCSarasota County Neighborhood AssociationsYou will notice that the neighborhood boundaries are different in each case; no one is incorrect, but it does show that residents relate differently to their place than the city or county defines their neighborhood.
  • We just covered five different types of boundaries. Now lets look at WHO is living in North Port. We will be looking at the total population, age, and race/ethnicity in North Port. We will use the census block boundary system to look at the data within the city, because it is the most local level (map on left).We will use the census block group boundaries to look at the data for the entire county, because the blocks are too small to identify patterns at the county scale (map on right).The map of Sarasota County shows there are a lot of people living in NP, esp in (this) BG.The map of NP shows that there are lots of blocks in this particular BG, which together add up to a lot of people for the BG.
  • At County scale, we see a lot of kids up to age 5 in NP compared to other parts of the county.Within the city, we can see where there are areas with more or less young kids.
  • This map shows patterns of older adults. As compared to the rest of SC, NP does not have as high a percentage.Within NP, we can see there are more around (____)
  • These maps show the patterns of people who identify as Black or African-American. There is a higher proportion in NP than in many other parts of the county. Within NP, spread throughout rather than concentrated in a few spots. This is especially striking compared to the City of Sarasota, where most people who identify as Black/African American are living in certain blocks and block groups.
  • Again, with people who identify as Hispanic / Latino, there are more people living in NP when you look at this county-scale block group map. There are people who identify as hispanic/latino spread throughout NP’s blocks.
  • As you can see, most people living in SC identify as White. Within NP, it might be hard to see from where you are but there are some real differences in the range of colors from block to block
  • So there are three important things to remember. 1) Understanding boundary systems is important - decisions are made according to boundaries.2) Boundaries are often different than the way we relate to one another in community3) When we zoom in to the block level, patterns in the community are more visible.
  • OK, so now that we have a clearer sense of how GIS mapping works and what North Port looks like, we are going to zoom out and take a look at some community indicators that relate to Sarasota County as a whole. The purpose is to show you some of the data that has been tracked over the past ten years, and to display it not just in graph form, but now in map form too. You have a sheet in your packet that lists over 150 community indicators that were tracked here in Sarasota County over the past ten years. Last year, SCOPE pulled together the data for a subset of these indicators and created a “Deck of Cards.” You have a set of these cards on your table, and you have a summary of them in your packets. Here’s how the cards are organized:At the top of each card is the definition of the indicator and the source of the data. If there are any caveats or considerations that are important to keep in mind, these are listed. On the left side of the card is the data for the whole county, in graph, chart, and map form. On the right side of the card if there is within county data available, this is provided in graph, chart and map form.On the back of the card, mapped data is provided over time – for the county in state context on the left, and for within the county on the right. At the bottom there is room to list associated indicators and patterns in the data. These are not provided by SCOPE but rather are intended to be completed by our community as a whole as people review and reflect on the data. In a minute, we are going to ask each table to take a look at the Deck of Cards and “notice what you notice.” What are the patterns that catch your eye? What stands out to you? We also will ask you to take a look at the full list of over 150 indicators that have been tracked over the past decade. Which of these do you hope that the community of Sarasota County will keep tracking because you think they are important to North Port, especially? Before you dive in, there are a few considerations worth keeping in mind, in order to spot meaningful patterns in the data.
  • A community indicator might not reveal important differences across identity groups. Let’s take a look at one indictor of health: infant health, in terms of low birth weight. Compared to other counties in Florida, Sarasota County has a relatively lower percent of babies born of low birth weight.That doesn’t tell the whole story, though.The rates were significantly different for babies of different racial/ethnic identities.Babies identified as Black have significanty higher rates of low birth rate than babies of other racial/ethnic identities. Also, over the past ten years, the rates have remained generally the same for babies most babies, except for babies who are Black – for these babies the rates increased in the middle of the decade, and then began decreasing. So one rate for the whole county doesn’t tell the whole story – in this case, it differs for babies of different racial/ethnic identities.
  • A single community indicator is often not sufficient to measure an aspect of well-being. Often it is not enough to examine just one indicator of well-being. Let’s consider another indicator of infant health: infant mortality rate.It looks like Sarasota has a relatively low rate of infant mortality compared to other counties in Florida.However, the trend line shows that over time, not only are the rates consistently higher for babies who are Black, but also in more recent years, the rates have been increasing for babies who are Black and White and Hispanic / Latino. Even if relative to other counties Sarasota County looks relatively better, relative to our own county, things appear to be getting worse.
  • It is important to examine the ways an indicator is changing for areas within the geography of focus.What we really want to be able to bring into focus are the patterns within our County. Sarasota County has relatively higher rates of graduation compared to other counties and the state as a whole, butWithin Sarasota County, very different rates for different school attendance zones.
  • Sometimes the fact that an indicator is NOT changing is noteworthy.Lower rates than the state as a whole, but the rates aren’t decreasing in Sarasota County, relative to the state as a whole.
  • Sometimes the rate of change relative to other scales is noteworthy. Higher rates of unemployment relative to the nation as a whole, with a clear change since 2008.
